2 plus 3 equals 5 7 plus 2 equals 9 6 plus 9 equals 15 8 plus 4 equals 12 9 plus 7 equals 16 Am I missing something here? Probably. You say 2+3=5, but the question clearly states 2+3=10. Why would it say that? Suppose you had only one hand. You count 1,2,3,4,5,10,11,12. That last doesn't mean "twelve" as we know it, Jim. It means one hand (5), plus 2 spare ones. We could say: if 2+3=10, 5+2=12.

-4 plus 10 equals 6.

x=10

12 + 10 + 11 equals 33

Yes, but on ly if you don't say "equals 10 " at the end.
