Cheryl packed 39 oranges and 98 apples for the class picnic. Use mental math to find how many pieces of fruit she packed.

uh... you know you're supposed to add mentally right?

Step-by-step explanation:

Even though this is one of the most r*tarded questions I've seen I will answer it anyway. Well, first in our head 3 + 9 = 12. Add the 0, so now we have 120. Whenever we have a nine anywhere it's always +10 then subtract 1 from the number you're adding it to. For example, 9+8 first we have 10 (if you don't know from where read above again), then we have 8-1, and 10+7=17. now add 17 and 120. You get 137. Your answer is 137

step-by-step explanation:

if x = 2 you have to find x to finish the problem
