... Formulas are very similar to equations. Consider for now only equations with one unknown variable , denoted by some letter, which can be x but can also be different. An equation is an equality between two mathematical expressions containing the unknown number (maybe in several places), as well as other numbers which are known. ... For instance--if you multiply two sides of a formula by the same number, the result is still a valid formula, even if what you multiply contains unknown numbers. ...
