When we perform operations to manipulate equations, some operations produce equivalent equations, while others don't necessarily produce equivalent equations. When we're solving an equation, we need to use operations that guarantee equivalence.

Dear Math, please grow up so you can solve your own problems.

I understand that math is really important but I don't need calculus and algebric formulae in my day to day life, just basic addition subtraction with multiplication and division, that's it. I wish I wasn't forced to learn it, I do find it interesting but until I find out why I am doing what I am doing I don't understand it, in math it feels like you make up rules as you go, "we do this because I said so".
