Repetition in Mathematics
In mathematics, repetition refers to the process of performing a mathematical operation or task multiple times. This concept is commonly encountered in various areas of math, such as arithmetic, algebra, and probability. Understanding how to recognize and apply repetition is crucial for solving mathematical problems efficiently and accurately.
Types of Repetition
There are several types of repetition that are important to understand:
- Repeating Decimals: A repeating decimal is a decimal number that has a pattern of digits that repeats without end. For example, the decimal representation of 1/3 is 0.3333... with the 3s repeating infinitely.
- Repeating Fractions: A repeating fraction is a fraction in which one or more digits repeat infinitely in its decimal representation. For example, the fraction 2/7 is equal to 0.285714285714... with the digits 285714 repeating.
- Repetitive Sequences: In algebra and sequences, repetitive sequences are patterns of numbers that repeat at regular intervals. Understanding the repetition in sequences is important for finding patterns and making predictions.
- Repetitive Operations: When solving mathematical problems, repetitive operations often arise, such as adding, subtracting, multiplying, or dividing the same numbers multiple times. Recognizing when to apply repetitive operations can simplify calculations and lead to efficient problem solving.
Study Guide for Repetition
To study repetition effectively, consider the following steps:
- Practice Recognizing Patterns: Work on recognizing patterns in numbers and sequences. Look for repeating digits, repeating fractions, or any regularity in mathematical expressions or equations.
- Work on Repetitive Calculations: Practice performing repetitive calculations, such as adding or multiplying numbers multiple times. This will help improve computational skills and efficiency.
- Explore Real-World Examples: Look for real-world examples of repetition in mathematics, such as periodic functions, cyclical patterns, or applications of repeating decimals in financial calculations.
- Use Visual Aids: Visual representations, such as number lines, grids, or diagrams, can help illustrate repetitive patterns and make them easier to understand.
- Seek Help When Needed: If you encounter challenges with understanding repetition, don't hesitate to seek help from teachers, tutors, or online resources to clarify concepts and solve problems.

The Number System
Know that there are numbers that are not rational, and approximate them by rational numbers.
Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number. [8-NS1]
Expressions and Equations
Work with radicals and integer exponents.
Use square root and cube root symbols to represent solutions to equations of the form x^2 = p and x^3 = p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational. [8-EE2]
