Okay, why does math involve letters? o_o Just to confuse people? o_O
The letters are symbols. It's better than having whole words put in, and much less confusing. For example this: c=3t+5 ...looks better than.... cost=3time+5
It's called algebra.
They are used to take the place of undetermined numbers.
just to confuse people .-. my opinion
I kno right!
Math isn't about numbers, it's about logic. I can see why that confuses you.
Because god hates humanity.
They are called Variables (which you should know) and are used to tell you an undetermined amount.
teaches you how to use variables like if you were missin a number in real life, then you could just plug it in and solve. simple
