Area use the formulas multiply Parallelogram Rectangle (Square) Triangle These formulas are NOT given to you on the test!!

Volume use the formula multiply This formula is NOT given to you on the test!!

Slope

Positive Slope the line goes up

Negative Slope the line goes down

Parallel Lines have the same … Slope

Nope, this is y = +xNope, this is y = ??Nope, this is y = +x 2 Use what you now about lines and parabolas.

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

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

Mode most Find the number that appears the most.

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 What is 25% of 60? (0.25)(60) =15

Scientific Notation positive # is a big # negative # is a small # must be greater than or equal to 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

when solving, there will be 2 answers

Equations or Inequalities Plug it in, plug it in…

Positive correlation (relationship)

Negative correlation (relationship)

No correlation (relationship)

Probability write as a fraction What you want Total

Pythagorean Theorem Tells us the lengths of the sides

Whenever you see a RIGHT triangle, think these numbers.
