They say only people with an IQ of 120 and over are able to figure this out in two minutes.

a² + ab

Add the numbers on the left of each = sign, then divide sum into the number on the right of the = sign. Each answer is the same as the first number on the left side (2,7,6,8). There’s the hint! Therefore, 9 + 7 equals 16 and then x 9 = 144. My I.Q. is in the lower range of 120 so it took me a little longer than 2 min. :)

OR a * (a + b)

[deoetdoctrinae]

I figured it out! 2 + 3 will never equal 10. That is like saying Obama + Pelosi equals conservative government.

Therefore, I disregard everything else, and come up with 9 + 7 = 16. :)

Yesterday I couldn’t spell mathematician, and today I are one!

What’s the question?

Really easy.

144. About 30 seconds.

I did it my way to prove that I remembered how to do a superscript. Haven't needed to do that since Ra^thergate.

[Roccus]

I went an entirely different direction

I saw that the sum of the two numbers times the first number equaled th “answer.”

Therefore, 9+7=16x9=144

[aruanan]

2+3=5, 5*2=10
7+2=9, 9*7=63
6+5=11, 11*6=66
8+4=12, 12*8=96
9+7=16, 16*9=144

I love giving my 5th grade students problems like these. They love them too. It is amazing how many of them will eventually figure them out. Even in public schools.

[ProudFossil]

Actually the correct answer is 12 squared.

[Poincare]

a^2 + ab = c works for the given eq’s and gives 144 for the question mark.

[allmendream]

LOL.

Took me about ten seconds to see the pattern.

But multiplying 16 by nine in my head (I work with paper damn it) I came up with 146 instead of 144 by the twenty second mark; but I thought that was wrong. So I mentally rechecked my math and came up with the correct answer a few seconds after.

So.... smart enough to see the pattern almost instantly, dumb enough to make a mistake multiplying 16 by 9 in my head, but smart enough to catch it.

By most IQ tests I score embarassingly high, as in, “why haven’t you done more with your life?

[navysealdad]

2(2+3) = 10
7(7+2) = 63
6(6+5) = 66
8(8+4) = 96

So...for 9+7
9(9+7) = 144

[Hot Tabasco]

Everybody coming up with 144?!?! LOL.. I don’t think so.

112......
