There are some sat math formulas that have to memorize SAT to SAT. This does not include SAT math formulas that are given to you at the beginning of each section of mathematics. Make sure you know who you are given options so you do not waste your time memorizing these! As for the SAT math formulas that are given to you and you have to memorize, here are some important examples:
Slope = (Y2 - Y1) / (X2 - X1) or (Change Y) / (X Change)
Exponent Rules: (m3) x (m4) = m7 and (m3) 4 = M12. Make sure you have memorized this difference because the SAT try to trick you.
= Percentage (part) / (set)
Percentage increase or decrease = (change in quantity) / (initial amount)
= Probability (part) / (set)
A simple way to think of questions is based on f (x) = y. (The number in parentheses next to the f is always the value of x and the number after the equal sign is the value of it.)
Remember that as a fraction goes to a higher power, the value becomes smaller.
Even just remember these few sat math formulas could make a big difference in your SAT score.
