All mathematical equation have a formula ... A mathematical formula is the order in which the equation should be answer... for example ... 2(22+2) the formula for solving this equation is (PEMDAS) Parentheses, Exponents, Multiplication, Division, Addition and Subtraction... So it will be used like this... Parentheses first and there is an Exponent( 22) ...so 2 to the 2nd power is 4 ... the equation changes now it look like this 2(4+2) now you can do what just in the Parentheses (4+2) = 6... but your not done yet there still a number ... any number that is not given a sign is assunmed to be Multipliction so your equation looks like this now 2 x 6 ... which will leave you with 12 for an answer ...
