Calculus is a type of math that looks at how numbers change over time. For example, you can use calculus to figure out the speed of something that's traveling. It also helps us figure out how to graph curves and solve difficult problems. In calculus, you learn about equations and derivatives, which are a way of measuring how quickly a number is changing. To learn calculus, you need to understand basic math like algebra and geometry.
