Hi, I'm Jimmy Chang and we're here to discuss how to multiply with zeros. Now, multiplying with zeros is a pretty straightforward concept in that there's a really nice principal involved with multiplying with zeros, and this simply this: Zero times any term, X, is going to give you zero. So, pretty much, that tells you that zero times anything is going to give you zero. So, no matter how small or large the term happens to be, the instant it's multiplies with zero, it automatically cancels itself out. So, for example, if you have one-hundred times zero, that's going to give you zero. If you have forty XYZ to the fifth times zero, that's also going to give you zero. And if you have something kind of creepy looking, like square root of X squared minus Y plus Z times zero, that's going to give you zero. So, the idea here is that once you know that you're multiplying by zero, you will get zero no matter what the term happens to be. And that's really a nice convenient tool, because it really helps simplify your problems if you happen to have zeros. So, I'm Jimmy Chang and that's how to multiply with zeros.
