Cheat Sheet
- Inverse Operations for Solving Linear Equations -
Start by applying inverse operations to isolate the variable: reverse addition/subtraction first, then multiplication/division - for example, solve 3x + 5 = 20 by subtracting 5 and dividing by 3 to get x = 5. Always substitute your result back into the original equation to verify correctness. Resources like Khan Academy and MIT OpenCourseWare highlight this as a foundational algebra practice.
- Distributive Property and Combining Like Terms -
Use the distributive property a(b + c) = ab + ac to simplify expressions before solving - e.g., expand 2(x + 3) to get 2x + 6, then combine like terms to consolidate the equation. Organizing terms helps prevent mistakes, especially when variables appear on both sides. This technique is a staple in algebra courses at institutions like University of California and Purplemath.
- Multi-Step Equations with Fractions and Decimals -
Clear fractions by multiplying both sides by the least common denominator or convert decimals to fractions to simplify calculations - this reduces errors and streamlines solving. For instance, multiply both sides of ½x - 3/4 = 1/4 by 4 to avoid working directly with fractions. Math education research from the National Council of Teachers of Mathematics (NCTM) emphasizes these strategies for accuracy and confidence building.
- Pythagorean Theorem Fundamentals -
Understand that in a right triangle, the squares of the legs sum to the square of the hypotenuse: a² + b² = c². Memorize perfect squares (1²=1, 2²=4, 3²=9, etc.) up to at least 15² to speed up calculations and recognize common triples faster. This core principle appears in geometry curricula from Euclid's Elements to modern resources like MathWorld at Wolfram Research.
- Applying the Pythagorean Theorem in Problems -
Use a² + b² = c² to solve real-world and word problems, such as finding the diagonal of a rectangle or determining the distance between two points on a grid. Label the legs and hypotenuse clearly, substitute known values, and solve for the missing side - e.g., if a = 3 and b = 4, then c = √(3² + 4²) = 5. NASA and engineering programs consistently apply these skills for practical measurements and design challenges.
