Properties of Equality Cheat Sheet
- Addition Property of Equality - When you add the same number to both sides of an equation, it stays perfectly balanced - just like two sides of a scale! This trick is super handy for moving terms around and isolating that sneaky variable. Give it a try next time you need to simplify an equation.
- Subtraction Property of Equality - Subtracting an identical value from both sides keeps the equation fair and square, so nothing tips over. It's a powerful move for clearing out extra terms and zeroing in on your variable. Watch how rapidly you can peel away layers of an equation!
- Multiplication Property of Equality - Multiply both sides by the same non-zero number, and the equality holds true - like doubling two clones in perfect sync! This is especially useful when you're tackling fractions or scaling up expressions. Harness this property to simplify messy denominators in a flash.
- Division Property of Equality - When you divide both sides by the same non-zero number, the balance stays intact - think of slicing a cake equally for friends. This move is essential for breaking down coefficients and slimming down equations. Next time you see a big coefficient, divide and conquer!
- Reflexive Property of Equality - Every number is equal to itself - no surprises there! It's the foundation of all equations, reminding us that a = a is always true. Keep this in mind as the ultimate self-check in your algebra toolkit.
- Symmetric Property of Equality - If one quantity equals another, you can flip them like a pancake: a = b means b = a. This flexibility lets you reorder equations for easier solving and clearer insights. Embrace the switcheroo to keep your math smooth.
- Transitive Property of Equality - Chain equalities together: if a = b and b = c, then a = c. It's like linking puzzle pieces - once they connect, the picture is clear. Use this to bridge gaps between multiple equations and discover hidden relationships.
- Substitution Property of Equality - Swap equal values into any expression: if a = b, you can replace a with b anywhere. This is your best friend when simplifying complex formulas or solving systems of equations. Get ready to substitute for success!
- Square Root Property of Equality - When two numbers are equal, their positive square roots match too: if a = b, then √a = √b. This comes in clutch for solving quadratics and checking answers. Treat it as your shortcut to unlocking squared mysteries.
- Distributive Property of Equality - Distribute a factor across a sum: a(b + c) = ab + ac, spreading the factor evenly like butter on toast. This property makes expanding and simplifying expressions a breeze. Master this move to crush algebraic expansions!
