By implication numbers in mathematics are positive unless stated otherwise. Where confusion may arise the positive or negative sign is shown for purposes of clarity. (+6) - (-7) = ? This would normally be written as 6 - (-7) = ? If the "7" were a positive number then the result would be :- 6 - (+7) = 6 - 7 = -1, but "7" is a negative number and subtracting a negative number is equivalent to adding a positive number. So, (+6) - (-7) = 6 + (+7) = 6 + 7 = 13
0
+6 - +3 = +3
6 - 10 = -4
Negative 4 minus positive 2 is equal to negative 6.
