6 - 4/2 = how do you work this problem out

Question

How do you work this number out?

Answer 1

It's the matter of knowing what order you perform each function.

Parentheses comes first.

Exponents come next.

Multiplication and division follow

The last is addition/subtraction.

 

So we have 6 - 4 / 2

No parentheses, no exponents, but we do have division: 4 / 2, and that becomes 2.

That leaves us with 6 - 2, and that equals 4
