Positive six: 6 or +6.
It's 0.
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
The sum of 7 and -8 is -1.
A plus times a plus is still a plus. Below is the way I remembered it: If there is not a minus sign, it is plus (positive). If there is 1 minus sign, it is minus (negative). If there are 2 minus signs, it is plus (positive).
