The word 'combination' is used when we talk about things that are made up of different things put together. For example, if you like pizza with mushrooms and cheese, you could say that the combination of mushrooms and cheese is your favorite. It can also be used in math when we talk about adding or multiplying numbers in different ways. For example, if you have three shirts and two pants, you can make different combinations of outfits by pairing each shirt with each pant.
