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 See the Related Links for more info on Order of Operations. 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.

4+(-49) = -45
-15 * 3 = -45

negative 45
45 minus -50 is 95.
45 minus -16 is 61.
Negative 22 is.

I work it out like this: (-2/15) - (-1/9) = (-2/15) + (1/9) ) [minus negative is the same as plus] = (-6/45)+(5/45) [change both to 45th as that is the lowest common multiple of 15 and 9] =-1/45 or negative1/45
