# Math ## Math Skills Modules

This group of modules provide you practical knowledge and demonstrate the application of math in manufacturing. Each module in this competency group builds on the one before it, giving you confidence as you develop your knowledge in a way that is logical and intuitive.

### Introduction to Basic Math

This module designed to teach you how to identify different branches of mathematics, use a calculator, and understand the importance of estimating an answer before calculating it (Estimated completion time: 0.7 hours).

### Arithmetic Operations

This module covers the four basic operations in math – addition, subtraction, multiplication, and division – along with basic symbols and terminology (Estimated completion time: 1.4 hours).

### Numbers and the Number Line

This module covers place values, the six different types of numbers, and how number lines will help you compare the values of numbers (Estimated completion time: 1.1 hours).

### Introduction to Fractions

This module is designed to teach you about fractions, the parts that make up a fraction, how to compare them, and techniques for finding the least common denominator and ordering fractions (Estimated completion time: 1.1 hours).

### Working with Fractions

This module will teach you how to convert improper fractions to mixed fractions, as well as simplify fractions and convert between fractions, decimals, and percentages. You will also learn to add, subtract, multiply, and divide fractions and solve word problems (Estimated completion time: 1.4 hours).

### Decimal Numbers

Upon completion of this module, you will be able to understand the power of tens; identify place values for decimal points; round decimal numbers; and add, subtract, multiply, and divide decimals (Estimated completion time: 1 hour).
