I'm actually seeing 3 answers
7,10,11
If A + B = some calculation (C), then
Where C is [ A+B+(A*B) ] THEN answer is 7
Where C is [ A+(B*B) ] THEN answer is 10
Where C is [ ((A+B)*B) - (A*A) ] THEN answer is 11
If A + B = some calculation (C), then
Where C is [ A+B+(A*B) ] THEN answer is 7
Where C is [ A+(B*B) ] THEN answer is 10
Where C is [ ((A+B)*B) - (A*A) ] THEN answer is 11

That's what I had until our local Carl Friedrich Gauss, aka AFF, threw that wrench at me.
I've forgotten most of my algebra, I just do it in my head.

How are you getting that?
4*1 + 4 = 8
5*2 + 5 = 15
6*3 + 6 = 24
7*4 ----
8*5 ----
9*6 + 9 = "63"
5*2 + 5 = 15
6*3 + 6 = 24
7*4 ----
8*5 ----
9*6 + 9 = "63"
