Addition and subtraction are inverse functions.

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

Adding and subtracting polynomials is simply the adding and subtracting of their like terms.
The answer is -2m
just add the negative of the polynomial, that is the same as subtracting it. For example, x^2+2x is a poly, the negative is -x^2-2x. So if we want to subtract x^2+2x from another poly, we can add the negative instead.

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.

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.
Adding and subtracting polynomials involves combining like terms, which is similar to calculating the perimeter of geometric shapes by summing the lengths of their sides. In both cases, you are essentially aggregating values to find a total. Just as you simplify expressions with polynomials to find a single value, you also simplify perimeter calculations to understand the overall boundary length of a shape. Both processes rely on clear organization and the ability to combine related components effectively.
When adding or subtracting fractions their denominators must be the same
