IQ Test

A friend of mine sent me a puzzle that only people with an IQ over 120 are supposed to be able to solve. It took me about 10 minutes with a paper and pencil. Middle Grandson, D, did it in 5 minutes - in his head. But then he cleaned up on 4th grade academic awards. Here's the test.

If:
2 + 3 = 10
7 + 2 = 63
6 + 5 = 66
8 + 4 = 96

Then:
9 + 7 = ????

  4. The hardest part wasn't even solving the pattern, it was multiplying 16 by 9...which took me like 10 seconds.

  6. too easy to solve add number of left side and multiply it with the first number i-e add 9 + 7 add nine and seven and multiply it with first number which is 9 and is 16 x 9 =144.

  13. Got another way:
    1.)square first number
    2.)multiply first and second numbers
    3.)add two answers together
    Ex. 2x2=4, 2x3=6, 4+6=10

  15. Add both and multiply with first
    eg.2+3=5,5*2=10
    so 2 +3=10
    9+7=15,15*9=135
    so 9+7=135

  17. It's abuse of mathematical notation, even if you insist on a pattern that gives the 144. An engineer calculating like this should avoid the avionics business.
