plus times plus = plus minus times plus = minus plus times minus = minus minus times minus = plus so when you subtract a number it is the same as adding its negative; for example 7 - 4 = 3 7 + (1)(-4) = 3
Positive 3 plus negative 5 minus negative 2 minus positive 4 is equal to -4.
(-3)-(4)=(-3)+4=1 Minus times minus equals plus. The reason for this we need not discuss.
