Numbers and Operations
-
There are five types of numbers: Natural Numbers, Whole Numbers, Integers, Rational Numbers, and Irrational Numbers.
-
Natural Numbers are positive integers starting from 1.
-
Whole Numbers are non-negative integers including 0.
-
Integers include all whole numbers and their negative counterparts.
-
Rational Numbers are expressed as fractions or decimals.
-
Irrational Numbers are non-repeating, non-terminating decimals.
-
There are six basic number operations: Addition, Subtraction, Multiplication, Division, Exponents, and Roots.
-
Addition and subtraction are inverse operations, as are multiplication and division.
-
Exponents represent repeated multiplication, and roots represent the opposite operation.
Algebra
- Variables are letters or symbols representing unknown values.
- Expressions are combinations of variables, numbers, and operations.
- Simplifying expressions involves combining like terms.
- Equations are statements that express the equality of two expressions.
- Inequalities are statements that compare two expressions using greater than, less than, or equal to.
Geometry
- A point is a location in space, represented by a set of coordinates.
- A line is a set of points extending infinitely in two directions.
- A plane is a flat surface that extends infinitely.
- Angles are formed by two rays sharing a common endpoint.
- Angles can be acute, obtuse, right, or straight.
- Degrees are used to measure angles, ranging from 0° to 360°.
Statistics and Probability
- Data can be qualitative or quantitative.
- Data visualization involves using charts, graphs, and tables to display data.
- Measures of central tendency include the mean, median, and mode.
- Probability is a measure of the likelihood of an event occurring.
- Probability rules include the complement rule and the multiplication rule.
- Conditional probability and independence are used to calculate the probability of multiple events.
Calculus
- Limits are used to study how functions behave as the input approaches a certain value.
- The concept of limits is essential for understanding calculus.
- Evaluating limits involves using direct substitution, factoring, or other methods.
- Derivatives measure the rate of change of a function.
- The definition of derivatives involves the limit of the difference quotient.
- Rules of differentiation include the power rule, product rule, and quotient rule.
- Applications of derivatives include optimization and motion problems.
- Integrals are used to calculate the area under curves or the accumulation of a quantity.
- The definition of integrals involves the limit of the sum of the areas of rectangles.
- Basic integration rules include substitution, integration by parts, and integration by partial fractions.
- Applications of integrals include finding area, volume, and work.
