•Subtract exponents•Upstairs guy minus downstairs guy•Reciprocal any negative exponents


Exponents outside the parenthesis


•Exponents multiply•Coefficients and some variables have an invisible 1 exp.


Mean


•Average•Add up all data points and divide by # of points


Median


•Line up all data points (smallest to largest)•Pick the guy in the middle (find the mean if there are 2 in the middle)


ModeModal


•# in a data set that you see most often•{1, 2, 2, 3, 2} mode=2


Absolute value equation


•Should have 2 answers•{ # , # }


Dependent events


•Something can only happen if something else happens


Independent events


•Something happening has no effect on something else happening
