Multiplication
Division
Adding
Subtracting
ex: Answer:

Quadratic Equation and formula
equation:
Formula in words: opposite of b Plus or minus the squareroot of b squared minus four times a times c all over 2 times a

Surface area of a cube

Volume of a cube

Slope Intercept form
(m=slope b=y-intercept)

slope is 2/3 , y-intercept is 4
Finding Slope from 2 points
(x1,y1)(x2,y2)

I Hope all these help
Good Luck
