What jobs uses related to linear algebra?

Answer 1

Whether you like it or not, basic algebra, and increasingly, linear algebra, are becoming so commonplace that people working at a fast food restaurant are finding the need for it. It's pretty much safe to assume that any class you have to take as a graduation requirement for High School is something you're going to be using no matter what job you get.

More advanced math, such as geometry, higher level algebra, trigonometry, calculus, and beyond, are also required in a very large number of professions - there's no way to list them all. For example, your boss at that fast food restaurant, who needs to be able to handle money, is doing more than just basic algebra - if he/she wants to figure out how fast their profits are growing each month compared to how fast they were growing last month, he/she will need to jump straight into calculus to figure that out. Architects and carpenters also use trigonometry on top of a solid geometry background, and programmers use varying levels of all of these skills on any given day, as do Accountants.
