Subtracting a negative is the same as adding the equivalent positive. For example, subtracting minus 10 is the same as adding 10.

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.

If the denominators are the same, just add or subtract the numerators. For example, 2/7 + 3/7 = 5/7. am i right?
