Math
Math can be interesting! This is oversimplified, but we can use math for many things. One is that might want to know the position of a motor. In electronics, we might want to know what part of an AC cycle we are in such as reading oscilloscopes. . What is even more interesting, we do not have to have some fancy computer language in most cases to calculate what we need. Then if you want to, you can port the code to a fancier language and or system.
