WombRaiders:
You are an slowpoke to the core.

The answer remains 6.

It is only when dealing with variables in algebra that the prefixed sign of negative or positive applies.

In simple Bodmas arithmetics (which stands for Bracket, Open, Division, Multiplication, Addition and Subtraction) the last operation to be carried out is subtraction!

Naturally, you would have multiplied first then added the value to the 3 to the left.

So what stopped your dunce head from adding the values to the right?

As I said the final operation to be done is to subtract the values to the right from that in the left.

Dunces like you do not even know the difference between simple arithmetic problems involving absolute values to that of algebra involving variable assigned values.

Go and ask your nephews and nieces in primary school to re- educate you.

Dunce

Na now I know say some people no even know the BODMAS wai them da shout, BODMAS stands for
B = BRACKET
O = OF or ORDER or OVER (not and never OPEN)
D = DIVISION
M = MULTIPLICATION
A = ADDITION
S = SUBTRACTION

if you do not know what the OF stands for, sometimes you will hear in word problem where they say

20 is 5 times OF 4, that is where it comes from.(i.e 20/4) OF

or when you see 20/4 - OVER (still the same with OF)

una still dey ds thread. Na wa ooo

sister, na CHANGE we da look for oh, aspa APC Things... we have to correct the result of bad educational system from Nigeria

WombRaiders:
Apply this rule with your calculator A + B = B + A and see if you will get the same answer.

Olodo.

Bros, abeg no vex oh, na which village you come from? because if na my village, thunder for don strike you with all these foolish maths and arguments way u da put forward.

A+B=B+A (Associativity)
if your calculator say e wrong, then that your calculator must come from your village as well

2+3 = 3+2 = 5
-2+3 = 3+(-2) = 3-2 = 1
2-3 = -3+2 = -1
-2-3 = -3-2 = -5
Try am for your calculator, if e wrong, then two things are involved, it is either your calculator is a villager or na you be villager, anyone wai e be, una no safe at all

Seventeen:
Bros am no mathematician, If 12 is actually d ans... *shrugging* fine
Like some of our funny naija brothers normally ask... "will the ans increase the value of naira?" .

Bros, it will go a long way to change the value of the Naira if you find yourself in Engineering of finance field.. Anywhere you find yourself, e go change the value of naira seff

Taiwosam:
Okay. Does your cousin reside in Yaba?

naah, he stays in Shogunle, or something like that about #200 not Yaba

Taiwosam:
Where did you stay on those three occasions? Do you know anyone in Lag? Accommodation seems to be my only concern now.

I stayed with a guy I met in the car the first time, now am staying with my cousin

swiftguy1:
Seems Class XII has a number of people from outside Lagos. This is going to be fun.
P.S are they no ladies in Class XII? Can't just stare at hardwares for the entire 2 weeks. Hope they gave us some softwares!

At all oh bros, there better be softwares oh, so person fit stretch body once in a while... I no fit shout, I want strong strong body at all

All the Engineers and Mathematicians in the house, please what did you get oh

BishopMagic it does not matter which one comes first, even though BODMAS says subtraction comes last, they actually have equal power in this case, so anyone you handle will go.

so

3+3*3-3+3 = 3+9-3+3

so if I handle the negative first, we can have
3+9-3+3 = 3+(9-3)+3 = 3+6+3 = 12
3+9-3+3 = 3+9 + (-3+3) = 3 + 9 + 0 =12
or if you handle the positive first
3+9-3+3 = (3+9)-3+3 = 12-3+3 = 12

All of you getting 6, your mistake is this, and I repeat
3+9-3+3 = (3+9) - (3+3)

I dare you to open the second bracket, and if you do not have
= 3+9-3-3, then you do not know maths, but if you get it, you will know that your method is wrong.

SirAlfred:
@Ramos16, this is not algebra, it is bodmas

chisus, guy why are you talking like this na, why? eh?

altamaurice:
This op funny...LWKMD...you write KPMG test dey form guru...lol...say you kill dragnet, anybody wey prepare write Kpmg test fail suppose chop cane cos na the easiest test to pass be that. If the firm no ley (hard) dragnet go just organise shakitibobo for you and you go write am say you bad abi? Naaah you no be legend; you be learner. Incase you wan test your skill write
1. Citibank graduate trainee test
2. Mckinsey pst test (that day I pee for trouser na that dey I know say 1/26 na good score)
3. Dragnet Gse test bad small sha

If you wan really test your skill google Talent Q...take the online test download the result then tell me where them place you...if you get average; You are a bad guy

lol... seriously, you pee? no be say I da form bad guy, I am just trying to boost peoples confidence, cos the truth be say I for fail the test with the kind of tension wai build inside me 2 days before the test, thats the truth, but I gained confidence back somehow, and I just want to do the same for people..

SirAlfred:
if you did not get 6, you are a product of special centre.

3+(3*3)-3+3
= (3+9) -(3+3)
=12 - 6
= 6 QED

Shut up my friend, na you be product of special centre for special case of mental disorder.

You do maths at all.

FYI:

(3+9) -(3+3) what happens when you open the second bracket

= (3+9) - 3 -3

which is not the same as 3+(3*3)-3+3

go learn your elementary maths well bro

Hoggy:
using a calculator would not give the right solution to the mathematical problem, the guy is right you always have to consider your bracket placing the answer is 18

chisus, 18 ke? which school you go na bros?

ehis4real1:
Answer=6. 3+3*3-3+3
3+(3*3)-3+3. BODMAS
3+9-3+3
12-6
6
Is like sum ppl don't knw hw 2 apply d rules of bodmas. Solve d multiplicatn fest b4 addition nd subtraction. Now apply it nd solve it

ogbeni, which kind of wahala you da cause for yourself, no go work for bank oh, or else you go loss all their money

Nicklaus:
do u know that -(3+3)= -3-3=-6 ? I ve been laughing at everyone and didn't want to comment. If these are the kind of graduates this country produces I m not surprise we are where we are

Ahhhhhhhhhhhhhhhhhhh, Brother na you know book pass Jare, no mind all these people. I have been looking for a way to explain it, but you have just captured it all, good one there.

You be teacher?

Very funny guys around here.

Meanwhile, this is how it is solved all numbers have signs in front of them that cannot be neglected, showing all the signs for the question it will look like this

(+3) (+3) x (+3) (-3) (+3) ........ eqn (1)

eqn(1) can also be written as

(+3) + [(+3) x (+3)] + (-3) + (+3) ...... eqn (2)

Now BODMAS

Brackets (allow the parentheses, only remove square brackets) i.e solve (+3) x(+3)

(+3) + (+9) + (-3) + (+3) ...... eqn (3) (if you disagree let me see your hands up)

There is no OFF, Division, Multiplication
so we move to the addition, we can add everything up apart from the one with the negative sign

= [+3++9++3+(-3)]
= [3+9+3-3]
= [15-3] = [12] = 12


No Long story

Please Note that the sign in front of a number belongs to that number exclusively and cannot be separated from it. If a number does not have a sign in front, it is implicitly positive.

Hence you can't do this
3+3 x 3 - 3+3 = 3+(3 x 3)-(3+3) {Wrong}

Rather it should be
3+3 x 3 - 3+3 = 3 + (3 x 3) + (-3 +3) {Correct}

Dogs are programmed to fear Snakes.

Yes they do, just like most animals, even lion, they will never attack the snake, but they will stay around barking to draw attention or scare the snake off

where is edward1984 and VeeBabs are you guys here, please come and analyze this snake for us here, some people are already jonesing here.

otr1:
Even a puppy knows what a snake is.
Why he waited for the snake still baffles me

You think dogs are like human beings, its funny how they behave, because even the most cowardly dog only really fears human, it will back at other animals no matter how big, or fearful even to death.

Burger01:
I'm sure the dog might not have seen the snake earlier enough to bark for attention before he got bitten by the useless snake. I hate snakes! Why did God bother to create them

he created them, so that you can hate on them....

stereo:
Hey, you're a smart guy ain't you? So I believe you'll understand my angle. You live in lagos or somewhere close to it. Now, compare yourself to someone who came all the way from abuja.

How many attempt is such a person likely to make?
Don't talk about passion cos I've got it.

Talk about the risk of travelling nearly 12 hours monthly. This doesn't favor a lot of people.

Did I make any sense at all?

I came all the way from Kaduna, its about 15 hours away, and this is my third time.

abbeyseto:
Hi guys(and ladies),
You see, for those that complained about being rejected despite their worth, and they feel it's all a joke. The recruitment section of Andela knows what they are doing.

For you to be a good programmer, you need patience and persistence. Know what you want and go for it no matter how many times you fail, only that; learn from each failure before attempting again.

This is like my 7th time of applying to Andela this year, and my third interview with them but from each application, i improve my self in preparation for next application.

Now, I'm going for class XII bootcamp on Monday.

Except you are not passionate about being a world class developer that's when you'll easily give up on opportunities like this.

Applying is not easy; I know that, but hey... You just need to know what you want and go for it.

Fellow prospective bootcampers, see you in JavaScript class on Monday.

JavaScript?

duvie92:
Don't get scared. Ruby is way easier than JavaScript just that it is extensive. Besides, you guys would be working with Sinatra, a web applications framework for Ruby developers that is so easy to learn. Jeff Wan, the trainer is a nice guy so no worries man.

Thank you bro, I was actually thinking that we will be using Ruby on Rails, so sinatra it is? or both?

danvery2k6:
People with some experience in programming are placed in other languages besides Javascript. You will be alright bro. You will make it. No cause for alarm.

God bless you my brother, I needed to hear that, you just boost my confidence now. God Bless

sname00:
Bro you on your own o, I was placed in javascript

mtchewww, this kind thing tire me, I told them I have only experience with little php, and that the first time I handled javascript was in codeacademy, I no know wetin this guys don do me like this oh, chai, wetin man go do na , RUBY!

I got a mail placing me in RUBY class, I do not know anything about Ruby, why would Andela do this to me na? anybody been to the ruby class? what should I know and learn, please help

AtomikEnergy:
o.p, how does your wife's salary concern u? Even if she earns one million dollars., a husband must not demand for a wife's salary unless she wants to give it to you. And to those who wives who give all your salary to your husband. Pls wise up, your husbands arent GOD.

hehe, you did not ask of my opinion na, I only placed the question so I see what people say, I experienced an issue and that is why am asking.

tgmservice:
Dear Andela

Bro, no vex, whenever you interview with Andela, just try to be outgoing as possible, smile like this , and look , that is all they need, plus they need to see that you are passion driven, years of experience don't really matter to them.

I believe it is a man's responsibility to provide for his wife, buy clothes, shoes for her etc. What happens to that responsibility when she is earning just as good as you are

Ladies and gentlemen I brought up a topic among my friends today, and I got variety of interesting opinions, but I will still love to know what nairalanders think.

In a family where the husband and wife have good jobs and earn well, what should happen to the salary of the wife?

For ladies, what will you do with your salary? will you hand it over to your husband at the end of the month, so he can decide on the fate of the money?

For Men, what do you expect from your wives? do you expect her to submit her salary, or use it for herself?

stereo:
You see what I'm saying Ramos16? People coming to lagos for this boot camp would be forced to seek accommodation for a 1% chance of getting into Andela.

Lagosians are at an advantage.

This complaint was made in the first few pages of this thread when the Co- founder gave opportunity to ask questions. And he promised to address it.

Anyway, I'm not hating. It's just common sense.

yeah, I reason with you, considering that am faced with the same challenge, its a large risk to take for such low probability of positive outcome. But what can we do bro, its not as if there is any company around that provides you with the same type of opportunity that Andela provides.. All we can do is hop on this one bus and hope we do not fall

stereo:
I guess the lack of accommodation is irritating(if that is true).
And Andela is kinda bias during the interview stages.

They barely ask most of the interviewees serious questions. It's based on who they like not just how passionate you are.

Good luck to the 1% for fellowship.

yeah, Its sure based on who they like and how passionate that person is, and its the same with all interviews too, its just the way it is, its psychology, even you will behave the same way if you were on the sit...
