jaz:
it is now that i appreciate all my maths teachers more and my parents for sending me to a good sch. Having A1 in maths from WAEC was clearly merited. Guys here saying 18 or 6 would clearly not pass any of the aptitude tests where i work. And later they'll say no jobs for naija.

SegunMike:


Lol ....I get...and I know we are all entitled to our opinions. But remember say na public forum where people around the world fit reach. Imagine the world reading this thread and seeing Nigerians as 'unintelligent' arguing over simple arithmetic ....but no probs, we all are prone to errors, I only hope you have realized yours sha.....Cheers.

6

simple bodmas

[3+(3*3)]-(3+3)

= [3+9]-6

= 12-6

=6

Olodos below me will say 12


For sake of all you olodos mentioning me here is a simplified explanation for you retarrds that I made on page 8

Seventeen:
Bodmas:
3+3×3-3+3=
3+(3×3)-3+3=
3+9[b]-3+3[/b]=
(3+9)-(3+3)=
12-6=
6

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?" .

coolio2014:
End this thread already! The answer is 12. Just type the question into google and see the answer... 3 + 3 x 3 -3 + 3.

All of you that chose something other than 12 and insulted peeps should come and apologize. Simple!

cute75:
EVERY BODY USE YOUR CALCULATOR AND UR ANSWER WILL BE 12....For those who don't know how to use BODMAS

hajlat:


You are wrong,the rule is to bracket addition before subtraction.Forget the fact that the minus sign is in front of 3.The minus sign is serving the outcome of whatever is in the bracket and not the 3.The 3 in the question is not -3 but - x(3+3) which is the same thing as -1x(6) which also equals -6. Therefore the answer is 6.
The solution is this
3+3x3-3+3
3+(3x3)-(3+3)
3+( 9 )-( 6 )
( 3 + 9 ) - ( 6 )
( 12 ) - ( 6 )
12 - 6 = 6 ans

adorable29:


My brother, I was shocked to the bones when I saw people coming up with crazy theories to prove that the answer is 6!



Goodness me!


I am not a mathematician but this is really embarrassing to me as a youth!Lol!

Even a primary 5 student can decipher the answer is 12.

Such basic mathematics, yet some people are complicating it and confidently for that matter!

repogirl:
Using BODMAS, the answer is 6.


OP sef 'fails' English woefully

anigbajumo:



Sir,u ar absolutely wrong

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.

BishopMagic:


Olodo bodmas implies that subtraction is carried out last.

Let me simplify it for you by substituting the value 3 for x

You will get the following :

X + X^2 - X + X

Note this is not a linear equation that must be equal to zero hence the rules of bodmas must be applied.

Therefore we must multiply first, then add before subtracting finally.

Hence we get:

[X + X^2] - [X + X]

[ X + X^2] - 2X

Substituting values for X = 3

[3 + 9] - 6

12 - 6

= 6


There is a reason why the OP stated that 95% of you will fail this simple test.

Olodo if you math is up to scratch, simply assign Y as the answer then do the differential in the substitute equation.

Thus:


Y = X + X^2 - X + X

dy/dx = 2X

Where the differential is the point value on a static linear scale i.e. the value on the x axis since we are not dealing with a linear curve


Substituting X = 3 we get the answer 6!

Go school una no gree go.

WombRaiders:


Calculator only enters the argument but does not follow bodmas.

Try using the same calculator working from the right to left of the equation and see if you get the same answer.


That is:

3+3 - 3*3 + 3

You will see that your answer will be zero.

The correct answer is 6.

Treat each value as absolute and use bodmas.

Using algebra rules for simple arithmetic shows you are retarrded.

WombRaiders:


Mind you, you are doing simple arithmetic and not algebra.

Remember your bodmas rules

airsaylongcon:


I hope you know that 3+3*3-3+3 is not the same thing as 3+3-3*3+3!

In the later case case it becomes 3+3-9+3 (multiplication has highest precedence)

Since we have all subtraction and addition we solve from left to right. (NOTE: It is a fallacy to say addition is done before subtraction. Both have equal precedence and are evaluated left to right)
6-9+3
-3+3
0

The calculator is correct evaluating to zero

WombRaiders:


As I said earlier A + B = B + A

Whatever you enter from the left or right should give you the answer but as we can see you have two answers 12 and zero depending on how you enter the values.

This is not a linear equation that results in two possible values but a simple straight arithmetic equation that has only one answer which is 6!

The problem most of you shouting 12 have is that you are applying algebra sign rules to simple arithmetic where all values as absolute!

The negative or positive sign does not apply numbers on each end of the number scale but rather is the main mathematical operator!

Try and understand first and foremost the difference between algebra and simple arithmetics then you will see the answer is 6!

It does nt up to dis level....

let me elucidate u,use any search engine in the world YER ANS IS 12.



Shikena.

olawalepopoola:
The answer is 6. BODMAS Step 1: Multiply 3 by 3 first. This gives nine Step 2: Add it to the 3. I.E. 9 plus 3. This Gives you 12 Step 3: On the Other side add 3 plus 3. This gives 6 Step four: Now subtract the 6 from 12. Answer = 12 (QED)

LordReed:


Enter the expression in a calculator and come back with the answer you got.

WombRaiders:


The answer is not 12.

As I have stated in this same thread use the same calculator only this time input the values from the right to the left and you will see you have another answer zero.

A simple arithmetic question like this can only have one answer it is when you are dealing with equation curves that you can get two values!

Use bodmas and make sure you subtract last and you will see that your answer is 6!

adorable29:



You are such an imb_ecile! Your parents I SWEAR wasted money on your education!

I blame the akara school you went to actually! Chai! This are our future leaders oooooo!


Shameless he goat! You an igbooo smoker, are you better than the scientific calculators and all the special mathematical computer apps that people have used on this thread that provided the answer as 12! Those who thought us the mathematics have suggested the answer as 12!

You, this mushin tout is calling them olodo! WHAT THE HECK DO YOU AN AFTERNOON GOVERNMENT SCHOOL DROP OUT KNOW! Hahaha!


3+3*3-3+3= 12!

BODMAS oooooooo! Olodo!


Oyibo no dey complicate matter the way African f00ls do!

Simple!

Start with MULTIPLICATION!

3*3 IS 9

GO ON TO ADDITION! Note here that all the numbers wit a POSITIVE SIGN IN FRONT OF IT ARE TO BE CONSIDERED (EVEN IF THERE ARE UP TO 1MILLIOON OF THEM). As long as you have taken care of the BODM, we can now FOCUS on the "A" (addition).... Hence

We have,

9 + 3 + 3 =15

We are done with "A" addition, let's now continue with "S", subtraction.

15 - 3= 12!

That is why even a pry school pupil can do it! Just follow the SIMPLE RULE OF BODMAS!



WHERE THE HELL IS BRACKET COMING INTO THE EQUATION FOR! YOU ALL ARE SO DUMMMMMB!

If bracket was gonna be an issue then the "B" (bracket) of BODMAS will have come into focus and would have been solved FIRST!


Geeeeeez!

Ramos16:
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}

WombRaiders:


You will never understand!

Before you start any bodmas equation you must first include brackets

Why did you choose to add to the right but neglected the case to the left?
