What is 13 minus negative 23 minus 180 divided 45 plus negative 40?

Answer 1

minus eight

13 - (-23) - (180 / 45) + (-40) = -8

That's assuming that the 180 was to be divided by 45 (its hard to write parentheses in text!)

The above answer is correct if you are following the standard Order of Operations, which are:

1. Exponents and Roots

2. Multiplication and Division

3. Addition and Subtraction

Another answer:

I read it as:

{[13-(-23)-180]/45} + -40 = -43.2

I divided first three numbers by 45, not just 180. That's just how I read it.
