The answer is -2m
adding its opposite?
Not always but they need to have the same denominators when adding or subtracting them.
Subtracting a negative integer is the same as adding its absolute value.
The denominators must be the same, the numerators can be different.
Adding and subtracting polynomials is simply the adding and subtracting of their like terms.
Addition and subtraction are inverse functions.

You subtract a polynomial by adding its additive inverse. For example, subtracting (x - y) is the same as adding (-x + y). Alternately, you can simply subtract similar terms - that is, subtract the coefficients (the numbers) for terms that have the same combination of variables.
Subtracting a fraction is the same as adding its negative.
Subtracting a negative is the same as adding the equivalent positive. For example, subtracting minus 10 is the same as adding 10.
You keep them the same if they have different bases

Addition and subtraction can be thought of as the same thing because subtracting a negative number is the same as adding it and adding a negative number is the same as subtracting it.
When adding or subtracting fractions their denominators must be the same
Ensure that the denominators are the same when adding or subtracting fractions.
