Seven minus a negative six equals a positive one
It depends. (a) a positive minus a smaller positive is positive, (b) a positive minus a positive of the same size is zero, and (c) a positive minus a bigger positive is negative. For example, (a) 8 - 6 = 2 (b) 8 - 8 = 0 (c) 8 - 11 = -3
The same as a positive one. If you are multiplying a positive number by a negative, the answer will be negative. If you are multiplying a negative number by a negative, the answer will be positive.
-9 minus +1 is -10.
3 minus -1 is 4.
-7--1=6. A double minus makes a plus.
100 minus -80 is 180.
