Study Notes
Quantitative Concepts
- Exponents and roots are fun and easy to understand if you know multiplication and division.
- An exponent indicates how many times a number (the base) is multiplied by itself (ex: 5⁴ means 5 multiplied by itself 4 times).
- Distribution: Exponentiation distributes over multiplication and division (e.g., (x × y)³ = x³ × y³), but not over addition (e.g., (a + b)ⁿ ≠ aⁿ + bⁿ).
- Multiplying equal bases: When multiplying powers of the same base, add the exponents (e.g., x⁴ × x² = x⁶).
- Dividing equal bases: When dividing powers with the same base, subtract the exponents (e.g., x⁵ / x² = x³).
- Zero exponents: Any number to the power of zero equals one (e.g., 5⁰ = 1).
- Negative exponents: A negative exponent means to take the reciprocal of the base raised to the positive exponent (e.g., 2⁻³ = 1/2³).
- Roots are the inverse of exponents. The square root of a number is the number that, when multiplied by itself, gives the original number.
- Square roots: The square root of a number is the value that, when multiplied by itself, gives the original number (e.g., √25 = 5 since 5 x 5 = 25).
- Cube roots: The cube root of a number is the value that, when multiplied by itself three times, gives the original number (e.g., ∛64 = 4 since 4 x 4 x 4 = 64).
Algebra
- Algebra uses letters (variables) to represent unknown numbers.
- Solve for variables by simplifying the equation as much as possible.
- Dividing by a variable is prohibited, unless you know it can't equal zero.
- FOIL (First, Outer, Inner, Last) is a method used to multiply two binomials(e.g., (x + 5)(x - 2) = x² + 3x − 10).
- Factoring expresses a quadratic expression as the product of two binomials (e.g., x² + 2x - 8 = (x + 4)(x - 2)).
- System of Equations: Two or more equations can be solved simultaneously.
- Substitution Method: Solve one equation for one variable and substitute that value into the other equation.
- Elimination Method: Add or subtract equations to eliminate one variable and solve for the remaining variable.
