Do the Math!
Try to solve this puzzle:
Apparently only people with an IQ over 120 are able to figure it out. Keep your brain active and think about it.
If:
2+3=10
7+2=63
6+5=66
8+4=96
Then 9+7=???
It's not that bad but you have to think about it. And no, it's not a joke or an unanswerable question. Good luck!

Re: Do the Math!
Same here. It took me 45 seconds to figure it out, which is probably much slower than you brainiacs.
Oh, I left out an hour.

Re: Do the Math!
Mark ... does this mean your brain is fried trying to figure it out. I'd be willing to PM you about how its done..... don't want to spill the beans here... LOL
Re: Do the Math!
144....
And here's the formula...
$result = $a * ($a + $b);
if we want to make it a loop out put...using php for example...
Then the list of results you can pick from?
10 + 0 = 100
10 + 1 = 110
10 + 2 = 120
10 + 3 = 130
10 + 4 = 140
10 + 5 = 150
10 + 6 = 160
10 + 7 = 170
10 + 8 = 180
10 + 9 = 190
9 + 0 = 81
9 + 1 = 90
9 + 2 = 99
9 + 3 = 108
9 + 4 = 117
9 + 5 = 126
9 + 6 = 135
9 + 7 = 144
