Perimeter add up all the sides add

Area use the formulas multiply Rectangle (Square) Triangle

Volume use the formula multiply

Slope

Positive Slope the line goes up

Negative Slope the line goes down

Parallel Lines have the same … Slope

Mean average Add up all the numbers and divide by the # of numbers

Mode most Find the number that appears the most.

Median middle Put the numbers in order, then find the middle number.

Reciprocal flip DOES NOT CHANGE THE SIGN!

Opposite change the sign. The opposite of a positive is negative The opposite of a negative is positive

% percent convert to decimal and multiply move the decimal 2 places to the left

Scientific Notation positive # is a big # negative # is a small # must be bigger than 1 and SMALLER than 10 move decimal to the RIGHT move decimal to the LEFT

Square Root symbol What # times itself equals the inside?

Absolute Value symbol makes the number positive NEVER negative
