Matt say he can find the sum of 45+50 without rewriting it explain how you can solve using mental math

It's 95 because 5 plus 4 is 9 and 50 plus 45 is 95

It is actually easier than it looks because one of the numbers ends in a 0 which make so your really just adding one number.

Here is the thought process; ok so 5 + 0 = 5 so the last number will be 5 and 4+5= 9 which will be the first number so 9 and 5 put together = 95

I hope this help you.

The correct answer is $90
