6 + - 1 = 5 Here is a little table to help with manipulating double signs. = + = - = - = + NB If no sign is given then read it as (+). So for the above sum we could write + 6 + - 5 = +5
If it's a positive number then the result will be negative. If it is a negative the result will be positive. +6/-1 = -6 -6/-1 = +6
(-6) - (+1) = -7
-6 + 7 = 1.
7 - 6 = 1
1, 2, 3 and 6
A negative can be thought of as being the opposite of something. The opposite of a negative is positive so the negative of a negative is positive. Example: (-2)(-3) = (-1)(2)(-1)(3) = (-1)(-1)(2)(3) = (-1)2(6) = (1)(6) = 6
6
No. For example, the result of 1/6 - 2/6 is not a positive fraction.
