how did you add subtract the given monomials?
Answer (1)
think of it like putting together or taking away things that are the same. For example, if you have 3 apples + 2 apples, you get 5 apples because they are the same kind. We only add or subtract things that match. In math, if you see 4x + 2x, you just add the numbers in front and get 6x. But if the letters are not the same, like 4x + 2y, you can’t put them together because they are different just like apples and bananas. So, we only add or subtract monomials that are the same kind.
