Hello there! Today I will be talking about combinations. Combinations in the context of math permutations and combinations. For today, I will cover combinations first and then we can talk about permutations in a different video. In mathematics, the definition of combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.

Yes I know, the definition looks like a mashup of words and doesn't really make much sense because you can't visualize it. I talk about what combinations is using coins at the beginning of the video and then cover a few practice problems that help you solidify your understanding of combinations. Let's jump right in.
