◉Convert fraction to percent. Answer: 1. Change to decimal (divide
numerator by denominator) 2. Multiply by 100
◉Basic % problem formula. Answer: Percent X whole = part (helps
always to turn percent into a decimal)
◉Percentage discount (tax) formula. Answer: 1. Change percent to
decimal 2. Multiply by og price 3. Add or subtract accordingly
◉Percentage increase/decrease formula. Answer: 1. Write amount
of increase/decrease as numerator 2. Write og amount as
denominator 3. Chnage fraction to percent
◉Multiply similar bases. Answer: Add exponents
◉Divide similar bases. Answer: Subtract exponents
◉Raising power to another power. Answer: Multiply exponents
, ◉Exponent is neg. Answer: Move it's base to denominator and make
exponent positive
◉PEMDAS. Answer: Parentheses, Exponents, Multiplication,
Division, Addition, Subtraction (M, D, A, & S in order they occur left
to right)
◉Inequalities. Answer: 2 expressions where 1 is more than or less
than (OR equal to) the other
◉Solving Inequalities w out exponents. Answer: Similar to solving
normal algebra equations
◉Solving inequalities: multiplication or division across inequality
sign by negative #. Answer: Inequality sign changes to opposite side
OR manipulate inequality to always have positive coefficient for
variable
◉System of Equations. Answer: 2 or more equations that are solved
at the same time (left side = right side)
◉Solving system of equations (variables need same coefficient but
diff signs). Answer: 1. Add equations together to eliminate a variable
2. Solve for remaining variable
