Study Notes
Basic Arithmetic Operations
- Addition involves combining two or more numbers to find their sum. The '+' symbol represents addition.
- Subtraction involves finding the difference between two numbers. The '-' symbol represents subtraction.
- Multiplication involves repeated addition of a number. The '×' or '*' symbol represents multiplication.
- Division involves splitting a number into equal parts. The '÷' or '/' symbol represents division.
Fractions
- Fractions represent parts of a whole. A fraction consists of a numerator (top number) and a denominator (bottom number).
- A fraction represents the division of the numerator by the denominator.
- Fractions can be simplified to their lowest terms by dividing both the numerator and denominator by their greatest common divisor (GCD).
- Mixed numbers combine a whole number and a fraction.
Decimals
- Decimals represent fractional values using a decimal point.
- Operations like addition, subtraction, multiplication, and division can be performed on decimals.
- Decimals can be converted to fractions and vice versa.
Percentages
- Percentages represent a fraction or ratio as a part of 100.
- Percentages are often used to express proportions or rates.
- Percentages can be converted to decimals and fractions.
Exponents and Roots
- Exponents represent repeated multiplication of a base number.
- Roots represent the inverse operation of exponents. The square root of a number is the number that, when multiplied by itself, equals the original number.
Algebraic Expressions
- Algebraic expressions use variables (letters) to represent unknown quantities.
- Expressions can be simplified using the order of operations (PEMDAS/BODMAS).
- Equations are statements that equate two expressions.
Geometry
- Geometry studies shapes, sizes, and positions of figures in space.
- Basic shapes include points, lines, angles, triangles, quadrilaterals, circles, etc.
- Formulas exist for calculating areas and volumes of different shapes.
Measurement
- Measurement involves assigning numerical values to physical quantities like length, area, volume, weight, and time. The fundamental unit depends on the quantity being measured.
Data Analysis
- Data analysis involves collecting, organizing, and interpreting data to draw conclusions.
- Data can be represented using tables, graphs, charts, and other visualization tools. This is crucial for identifying patterns and trends in data.
- Statistical measures, like mean, median, and mode, are used to summarize and describe data.
Number Systems
- Number systems encompass different ways of representing numbers.
- Different number systems include natural numbers, whole numbers, integers, rational numbers, irrational numbers, and real numbers.
Ratio and Proportion
- Ratios compare two quantities using division.
- Proportions equate two ratios.
Order of Operations (PEMDAS/BODMAS)
- PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction) is a set of rules determining the sequence in which mathematical operations are performed.
Problem Solving
- Problem-solving involves applying mathematical concepts and techniques to find solutions to quantitative situations.
- Logical reasoning and critical thinking are essential for problem-solving.
- Breaking complex problems down into smaller parts is often helpful.
Sets
- In advanced mathematics, sets are collections of objects.
