Only when you're working on parallel universes
I quit math after they introduced imaginary numbers. I kept arguing with the teacher saying that if the numbers are only imaginary then how can we know the result is real???
Other than that I use to love algebra. Math in general strengthens us our cognitive ability. For example the ability to get into a car and navigate ourselves around, find shortcuts etc. For example, without math, you wouldn't have the computer in front of you. Without 1s and 0s and having the ability to know 0,2,4,8,16,32,64, for RAM and such IT people would not exist.
It also has use with our bank accounts. Having algebra allows you to say to yourself: I can afford to put away $200 per month. I need to save $1500 for my Spring Break. How many months will it take to save this much?
So then 200 * x = 1500...so then x = 7.5 months.
