Math Basics: Numbers and Operations

Numbers and Counting

• Numbers represent quantities or positions.
• Counting determines the quantity of objects.
• Numbers order objects or events.
• Systems like decimals or binary are used for counting.
• Numbers can be expressed as words, digits, or symbols.

Addition and Subtraction

• Addition combines numbers to find the total.
• Subtraction finds the difference by removing one number from another.
• Addition and subtraction are inverse operations.
• Examples: 5 + 3 = 8, 8 - 3 = 5
• Essential for more advanced math.

Multiplication and Division

• Multiplication is repeated addition (shortcut).
• Finds totals in equal groups.
• Division is the opposite of multiplication.
• Separates a total into equal groups.
• Examples: 3 x 4 = 12, 12 ÷ 3 = 4
• Critical for real-world problem-solving.

Fractions

• Fractions represent parts of a whole.
• Written as numerator (top) over denominator (bottom).
• Numerator shows the considered parts.
• Denominator shows total equal parts.
• Example: 1/2 (one-half)
• Can be simplified to lowest terms.

Decimals

• Decimals represent parts of a whole (like fractions).
• Decimal point separates whole and fractional parts.
• Example: 0.5 = 1/2
• Used for measurements and money.

Shapes and Measurement

• Geometry studies shapes (circles, squares, triangles).
• Shape properties (angles, sides, vertices) help describe them.
• Measurement finds the size or amount.
• Common measurements: length, area, volume, time.
• Tools like rulers, protractors, and scales are used.

Patterns and Sequences

• Patterns are repeated sequences of numbers, shapes, or objects.
• Sequences are ordered lists with specific rules.
• Identifying patterns helps predict future values.
• Examples: 2, 4, 6, 8, 10 (increasing even numbers); AABBCC color pattern.

Problem Solving

• Understanding the problem, identifying data, choosing operations (addition, subtraction, multiplication, division), and checking the answer are crucial.
• Break down complex problems into smaller steps.
• Diagrams or drawings aid visualization.

Order of Operations

• PEMDAS/BODMAS order is essential for accurate calculations.
• Parentheses/brackets first, then exponents, multiplication/division (left-to-right), and addition/subtraction (left-to-right).

Place Value

• Place value shows a digit's value based on its position.
• Each place (ones, tens, hundreds,…) has a specific value.
• Understanding is vital for reading, writing, and comparing numbers.
