"you’ll need to know this math formula later in life"
It should say:
"You lied TO SOME PEOPLE. Because some people are not going into a STEM field. For people who are, that formula is the basis of some part of their studies and they have to know it by heart to do everything else.
A-fucking-men. I’m sick and tired of seeing so many people say “man why did I even need to take these math classes? I’ll never need to apply this later on.” For some people, this is true. HOWEVER, some people don’t realize just how often they use basic math functions such as “solve for ‘x’” on a daily basis. Seriously though, learn yo goddamn math and apply that shit. I don’t want to have to fucking give you a calculator for basic addition/subtraction, tell you how much change -you- owe me when I’m giving you money for pizza, or see you google the answer for some simple multiplication/division -‘real-life’- problem.
