So what we're going to do is in the start folder, let's open up the calculations folder and we'll use calc_start, and you can see, I have a variable named x that we're going to use in some of these examples. So I'll uncomment that, and I'll also uncomment the modules I'm going to need. Let's start with the absolute value function, which returns the value of a given argument, stripped of any positive or negative sign. So I'll call math.abs on x. And I'll do the same thing on minus x. And let's also try out the pow and x functions. So the power function, I'll call math.pow. And that raises x to the given power. So we'll raise x to the second power. And then for the next example, we're going to use the math.exp function, which raises e to the x power. And let's just…
