Study Notes
Algebra Properties and Definitions
-
Associative Property: Focuses on grouping in addition and multiplication;
- (a+b)+c = a+(b+c)
- (ab)c = a(bc)
-
Commutative Property: The order of addition or multiplication doesn't affect the result;
- a+b = b+a
- ab = ba
-
Distributive Property: Connecting multiplication over addition;
- a(b+c) = ab + ac
-
Zero Property: Any number multiplied by zero results in zero;
- x O always equals zero
-
Identity Property: Adding zero or multiplying by one doesn't change the value;
- a+0 = a
- a*1 = a
Types of Numbers
- Real Numbers: Includes all rational and irrational numbers.
- Rational Numbers: Can be expressed as a fraction.
- Irrational Numbers: Cannot be expressed as a fraction.
- Integers: Whole numbers including their negative counterparts.
- Whole Numbers: Natural numbers plus zero.
Mathematical Operations and Expressions
- Difference: The result of a subtraction operation.
- Sum: The result of an addition operation.
- Product: The result of a multiplication operation.
- Quotient: The result of a division operation.
- Evaluate: The process of substituting a value for a variable in an expression.
- Simplify: Combining like terms in an expression.
Expressions and Equations
- Algebraic Expression: Contains variables, numbers, and operations.
- Numerical Expression: Consists solely of numbers and operations.
- Equation: A mathematical statement with an equals sign.
Special Numbers
- Variable: A symbol (often a letter) representing an unknown number.
- Like Terms: Terms that share the same variable in an expression.
Fraction Types
- Proper Fraction: A fraction where the numerator is less than the denominator.
- Improper Fraction: A fraction where the numerator is greater than or equal to the denominator.
Line and Slope Concepts
- Linear Equation: Graphs as a straight line on a coordinate plane.
- Slope Intercept Form: A linear equation written as y = mx + b.
- Slope: Determined by rise over run; measures line steepness.
-
Point-Slope Form: Describes a line using a point and slope;
- y - y1 = m(x - x1).
Special Properties
- Additive Inverse Property: a + (-a) = 0.
- Multiplicative Inverse Property: a/b * b/a = 1.
- Zero Product Property: If ab = 0, then either a = 0, b = 0, or both.
Sequence and Standard Formulas
-
Arithmetic Sequences: Defined by
- an = a1 + (n - 1)d where d is the common difference.
- Standard Form: Expressed as Ax + By = C.
