My father who volunteers to teach english to ESL adults often have grade level math homework. They brought this table in with no other instructions other than "fill out the rest"

He and I are confused. What the fuck?

by the way the numbers were already listed on the problem
i am guessing we need to figure out the top two middle row numbers, then the entire left side column numbers

I see no obvious correlation in the columns / rows...this is supposed to be gr.2 math? I only remember gr.2 math being like addition / subtraction within 100s, not looking at intercorrelation between rows of numbers lol

I didn't do this kind of math in grade 2 or any grade.

Lol what is this!!
