Why do skydiving needs math?

Answer 1

There not too much math involved. The only thing you need to be able to do is read the numbers on an altimeter. Fortunately, the altimeter face looks like a clock so it should be familiar to most people. Choosing altitudes can use some minimal math skills. For example; you want to make a ten second free fall and you know that the drop zone wants you to open at three thousand feet. In ten seconds you will fall 1,138 feet, so you would have to jump at 4,200 feet or higher to open at an appropriate altitude.
