than addition and subtraction.

So it is processed as 6 - (1*0) + (2/2) = 6 - 0 + 1 = 7

Any number times zero equals zero!

There were no parenthesis in the given problem, so it must be solved from left to right. Silly folks above think 0 x any number is that number! JimmyCrickets!

I originally said zero, but changed my mind and decided that I'm still extremely math challenged.

OK, edited again to say "1"

But still math challenged...
