If you subtract a negative number from another number, this is the same as adding a number. The two negative actions cancel each other out.

Whenever you are subtracting a negative from a positive (9 - -3) you can turn both negative signs into a positive so the new problem is 9+ +3 = 12
hope that helped
Negative 12 minus 3 plus 9 is equal to -6
minus 21 think of it as 12+9 which equals 21 then just whack a minus sign infront
3 minus -9 is 12.
-12 - (-3) Two negatives equal a positive. So, -12 + 3 = -9
9 - -3 = 9 + 3 = 12 12 - 8 = 4 9 - -3 - 8 = 4
9 + 3 = 12
-12 - 3 = -15
(-9) / 3 = -3 . Minus nine divided by three is equal to minus three
3 minus -6 is 9.
It is 3/4 minus 1/3 is the same as 9/12 minus 4/12 = 5/12
9/12 - 6/12 = 3/12 or 1/4
11/12-1/6 = 11/12-2/12 = 9/12 or 3/4 in its simplest form.
