gathering of principalities...

brytandre:
A degree in maths is uncommon sense, I'm sure u know that too. Well was talking to M.sc holder in applied maths, waiting on his response

wonda26:
I weep for you. Plz expand the expression you just wrote.

brytandre:
My guy, that's simple quadratic equation na.

(10+10)(10-10)= 10(10+10)-10(10+10)

= 10^2+10^2-10^2-10^2

At this point he took out the two middle terms only (I.e 10^2-10^2) by subtracting them

= 10^2 - 10^2

.

So it is correct!

wonda26:
10^2 - 10^2 = (10 + 10)(10-10) is very correct.

In mathematics, it is called 'Difference of two squares'


If you doubt, try simplifying the right hand side of the equation

If we buy one parrot for #1, we will be left with #99 to buy 99 birds.

using a long method of trial and error to get d right proportion of it will lead us to spending #95 to buy 19 peacocks and spending the remaining #4 to buy 80 pigeons.

akinsadeez:
very good attempt but wrong. If we use BODMAS, addition cones before subtraction meaning ur equation would give us

3(11-15) = 3(-4) which is obviously not equal to 24.

[size=15] There are five people. One of them shot and killed one of the other five.
Clues
1. Dan ran in the NY city marathon yesterday with one of the innocent men.

2. Mike considered being a farmer before he moved to the city.

3. Jeff is a top notch computer consultant and wants to install Ben's new computer next week.

4. The murderer had his leg amputated last month.

5. Ben met jack for the first time six months ago.

6. Jack has been in seclusion since the crime.

7. Dan used to drink heavily.

8. Ben and Jeff built their last computers together

9. The murderer is Jack's brother. They grew up together in Seattle


If you were the detective, tell us who the murderer is, and who was murdered. [/size]

akinsadeez:
Nice attempt but Wrong answer. You can only use each number once in d equation. The answer is actually very simple.

nizzyong:
solution.
let mother=x
daugther=x/2
father=x+5
then, x+x/2+x+5=100
LCM =2
2x+x+2x/2=95
2x+x+2x=190
5x=190
5x/5=190/5
x=38
:-! mother=38
daugther=38/2=19
father=38+5=43
:-! 38+19+43=100.

This is a Mathematics brain
test...

A girl went to school and the
teacher asked how old are you?

She replied I don't know bt I
know that I'm half my mother's age.

The teacher asked OK how
old is your


Welldone!!!! These are the kinds of things we need in our country, some serious mental development. I look forward to a more difficult one.


She said
I don't know but I know that my
dad is 5 Years older than my mother.

The teacher, then ask how
old is your dad?

She said I don't know but I know that if we add
our ages the answer is 100 yrs...

Now how old is the girl, her mum,
& her dad?

Stress ur brain a little. If u fail u
make me ur profile pix 4 2days. Your time starts now... happy
sunday everyone...

My final solution, note that the second solution might not be completely correct in all aspect because 0/0 =infinity

Abeg this one hard o. As you ask me, na imm i run go ask google. Apparently, there are a lot of possible answers:



Answer:

The letter H can be formed using 3 matchsticks,
The letter O with 4 matchsticks,
The letter T with 2 matchsticks,
The letter E with 4 matchsticks and
The letter L with 2 matchsticks

So total of 15 matchsticks are used.

This would remain true for all the possible answers.

Possible Answer 1:

She removes the horizontal matchstick from H so that it becomes 1 1.

Which will make it look like 110 TEL.



So it could be that she will call (telephone him at 11 0 Clock) or she will tell him the reason at 11 O clock.

Possible Answer 2:

She removes the horizontal matchstick from T so that it becomes l.

The boy reads it upside down so it can be 7310H…..Probably to say that she was there but was in room no. 7310 in the hotel.

Or she was there at 7:31 (May be later than the decided time)

Possible Answer No. 3




Below are other answers i know is not the answer to this particular riddle since we were asked to remove one stick ONLY and nothing else.



Now this 2 cases go with the riddle, if we are allowed to rearrange the letters and maintain the number of matchsticks as 15, there’s one more possibility.

The girl removed one matchstick from the letter O and rearranged the three matchsticks into letter A which makes the word HOTEL into HATEL.

Then the girl put the matchstick into the letter L to form the letter U which transformed HATEL into HATEU or HATE U which is the precise answer of the girl to the boy.

Possible Answer No. 4

She rearranges the horizontal matchstick to diagonal to make it look like N.

Which would make it “NOTEL”

So probably her parents said NO (No-Tell)
