# Yet another simple math problem

There seems to be a trend lately for simple math problems. So here is my version. It's super simple:

$23 + 62 = 94$
$41 + 22 = 36$
$10 + 20 = 21$
$50 + 17 = 22$
$67 + 96 = 172$

Problem:

$99 + 99 = x$

What is the value of $x$?

• it is 198. All your above additions are wrong. :P – Sid Dec 15 '17 at 17:07

198

Explanation

23+62=94. // (6+3)(2+2)
41+22=36 // (2+1)(4+2)
67+96=172 //(9+7)(6+6) =16(12)
// carrying one gives us 172

Similarly

99+99=198

• when I did arithmetic (6+3)(2+2) = 36 not 94 – Jasen Dec 17 '17 at 2:40
• also you have not explained 50+17 – Jasen Dec 17 '17 at 2:41
• (0+1)(5+7)=1(12) carry one gives 22 – rudra Dec 17 '17 at 2:45

Easiest way to look at this is

Reverse the first number then add to the second

I know this is the same as the other answers, but it explains the

99+99 case much better than (9+9)(9+9) which should be 1818.

• This also explains 50 +17 better than the other answers. – Jasen Dec 17 '17 at 2:42
