Negative 22 is.
23 hours 15 minutes minus 45 minutes is 22 hours 30 minutes.
13/15.
8:08 - 0:45 = 7:23
45
45 minus -16 is 61.
45 minus -50 is 95.
45 - 15 - 15 = 15
1,718 minus 23 is 1,695.
23
90 - 45 = 45
45 - (9%) = 40.95
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.
