And in this video in particular, we will explore modeling population. Modeling population. We're actually gonna go into some depth on this eventually, but here we're gonna start with simpler models. And we'll see, we will stumble on, using the logic of differential equations, things that you might have seen in your algebra or your pre-calculus class. So on some level, what we're going to do here is going to be review, but we're gonna get there using the power of modeling with differential equations. So let's just define some variables. Let's say that P is equal to our population.
