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

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
Well, darling, when you subtract a negative, it's like adding a positive. So, 6 minus a negative 4 is the same as 6 + 4, which equals 10. Math doesn't have to be a headache, honey!
it equals negative 13. We are learning bout this so i am very sure that's correct. .

No. If x = -2, then y = -(2x) -(+6) = -2*(-2) - 6 = +4 - 6 = -2
Negative 4 minus positive 2 is equal to negative 6.

6
It is: 10--6 = 16 because --6 is +6
Minus a negative means you can plus a positive so therefore the answer would be positive 8.
positive 5 minus positive 11 = negative 6
The answer to -12x minus 17 equals negative 89 is x equals 6.
