Study Notes
Key Mathematical Concepts
- Factors: Numbers that multiply together to yield a product in a multiplication problem.
- Product: The result obtained from multiplying factors.
Properties of Multiplication
- Commutative Property: Changing the order of factors does not alter the product. For example, 3 × 4 equals 4 × 3.
- Multiples: These are products generated by multiplying a given whole number, often identified through skip counting.
Mathematical Structures
- Array: An organized arrangement displaying items in rows and columns, facilitating visualization of multiplication and factors.
- Columns and Rows: In an array, columns refer to the vertical placements, while rows indicate horizontal placements.
Number Types
- Prime Numbers: Defined by having exactly two factors: one and itself. Examples include 2, 3, 5, and 7.
- Composite Numbers: These include all numbers that are not prime; they possess more than two factors.
Miscellaneous Concepts
- Exponent: A notation indicating repeated multiplication of a factor, simplifying computations (e.g., 3² means 3 × 3).
- Square Number: The product of a factor multiplied by itself, such as 4 (2 × 2) or 9 (3 × 3).
- Factor Tree: A visual tool that breaks down a composite number into its prime factors, illustrating its factorization.
