I'm not a therapist math stop making me solve your problems

Jack has none

the page number is also the answer

If billy has 8 apples, and john has 7, calculate the mass of the sun

I am Jack's math problem.

One time in the 1st grade we had a problem "If Anna has 5 apples and Ivan gives her 4 how manny apples does Anna have?" and I wrote "Anna has 9 bananas."....yep

Or maybe it was just a typo

I would've just written that he has "x" stickers

i would have failed,becouse i didn't notice the first time reading..

The answer is the number of the page

13x + 10 = y
