    Study Notes

    Properties of Equality

    • Addition Property of Equality: Adding or subtracting the same number from both sides keeps the equation valid.
    • Multiplication Property of Equality: Multiplying or dividing both sides by the same number preserves the equation's equality.

    Inverse and Identity Properties

    • Additive Inverse Property: Adding opposites yields zero, aiding in solving equations.
    • Multiplicative Inverse Property: The product of a number and its reciprocal equals one.
    • Additive Identity Property: The sum of any number and zero is the number itself.
    • Multiplicative Identity Property: Any number multiplied by one remains unchanged.

    Solution Concepts

    • Solutions: Values that satisfy the equation, making it true.
    • Equivalent Equations: Different equations that yield the same solution set.
    • Isolate the Variable: Rearranging an equation to have the variable alone on one side.

    Terms and Expressions

    • Terms: Components of an expression linked by addition.
    • Like Terms: Terms sharing the same variables with identical exponents.
    • Constant Term: A term that represents a fixed number without any variables.
    • Coefficients: Numbers that multiply variables in terms.

    Properties of Operations

    • Commutative Property: Order of addition or multiplication can be changed without affecting the result.
    • Associative Property: Grouping in addition or multiplication does not influence the outcome.

    Other Mathematical Concepts

    • Distributive Property: Allows multiplication of a number outside parentheses with each term inside.
    • Unit Conversion: Process of converting measurements from one unit to another.
    • Equivalent Expressions: Different algebraic forms representing the same value or outcome.

    Equations

    • Equation: A mathematical statement asserting the equality of two expressions.
