One way to define subtraction is: subtracting means to add the additive inverse of the number to be subtracted,
More formally, if a and b are numbers, a subtract b ( wriitten a - b ) means
a + (-b) where -b denotes the unique number such that b + (-b) = 0.
Summary: a - b = a + (-b) .
Comment: This definition is more useful for theory than practice. Students are usually taught how to subtract and then use that knowledge to add negative numbers.

Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does.
