Pre-Algebra & Pre-Calc Cheat Sheet
- Order of Operations - Think of PEMDAS as your trusty math recipe: you always tackle Parentheses first, then Exponents, roll through Multiplication and Division left to right, and finish with Addition and Subtraction left to right. This sequence keeps your calculations neat and prevents number chaos from breaking out. OpenStax Prealgebra Key Concepts
- Laws of Exponents - Exponents can be your best friends once you know the rules: the Product Rule adds exponents when you multiply like bases, the Quotient Rule subtracts them when dividing, and the Power Rule multiplies exponents when you raise a power to another power. Mastering these shortcuts lets you simplify complex expressions in a snap and level up your algebra toolkit. Effortless Math Pre‑Algebra Formulas
- Quadratic Formula - The quadratic formula
x = (-b ± √(b² - 4ac)) / (2a)
is like a secret codebreaker for anyax² + bx + c = 0
equation. Plug in your a, b, and c, and voilà - you get the two possible x solutions faster than you can say "quadratic." It works every time, even for those trickiest curves. QuizGecko Key Precalculus Formulas - Distance Formula - When you need to find the straight-line distance between two points (
x, y
) and (x₂, y₂
), the formulad = √[(x₂ - x)² + (y₂ - y)²]
has your back. It's basically the Pythagorean Theorem in disguise, measuring the hypotenuse of a right triangle on your coordinate grid. Crunch those squares and roots to figure out how far apart two points really are. QuizGecko Distance Formula Guide - Midpoint Formula - Want the exact halfway point between (
x, y
) and (x₂, y₂
)? Just average the x's and the y's: ((x + x₂)/2, (y + y₂)/2
). In one formula, you get the perfect meetup spot between two coordinate pals. Use it to bisect line segments or find centers of shapes! QuizGecko Midpoint Formula Tips - Slope‑Intercept Form - The classic
y = mx + b
makes graphing lines a breeze: m is your slope (steepness) and b is the y‑intercept (where the line touches the y‑axis). Just plug in m and b, draw your line, and watch linear equations unfold visually. It's the easiest way to turn algebraic data into a picture. CourseSideKick Linear Equations - Point‑Slope Form - When you know a point (
x, y
) on the line and the slope m, point‑slope formy - y = m(x - x)
steps in like a precision tool. It's perfect for building an equation around specific info without hunting for the intercept. Great for modeling lines through known points or applying transformations. QuizGecko Point‑Slope Insights - Absolute Value - Absolute value
|x|
measures the distance of x from zero on the number line, ignoring direction. So whether you have| - 5|
or|5|
, both equal 5, because distance never goes negative. It's super handy for solving equations and inequalities that involve magnitudes. Effortless Math Absolute Value Basics - Functions - A function is like a vending machine: you insert an input, and it dispenses exactly one output every time. The domain is the set of all valid inputs, and the range is every snack (output) you can get. Understanding functions powers up your ability to map real‑world relations in algebra and beyond!

- Law of Sines - In oblique triangles (no right angles here!), the Law of Sines
sin A/a = sin B/b = sin C/c
helps you solve for unknown sides or angles with ease. Match up your sines with their opposite sides, cross‑multiply, and solve - it's geometry made friendly. Ideal for surveying, navigation, and any adventurous triangle quests. OpenStax Precalculus Key Concepts
