Learn about the fundamental structure of numbers and the basics of algebra in this free online course.

Mathematics is an exciting and varied subject that can open up many opportunities for you. Studying maths (or math) makes you better at solving numerical and analytical problems and gives you skills that you can apply in many different job roles. This course on number operations and algebra will guide you through an introduction to the foundation of math, ranging from sets and Venn diagrams to fractions and algebra. Algebra is a powerful tool for problem-solving in science, engineering, economics, finance, architecture, ship-building, and many other day-to-day tasks. The skills you develop while working on mathematical functions will develop your problem-solving abilities in other ways, such as pattern spotting and logical reasoning.

This course introduces you to the vocabulary and definition of working with sets. Being familiar with the terminology helps you grasp the different concepts covered by the material. Venn diagrams show the relationship between a finite collection of sets. We will consider operations between sets as illustrated with the help of Venn diagram examples, and analyze the different types and orders of mathematical operations. Number lines are necessary as they present numbers in real life. Primarily because you can represent negative numbers in a way that makes sense, learn about number lines and graphing, a visual representation of the set of real numbers. Integers are the numbers that can be positive, negative or zero but cannot be a fraction. You use these numbers to perform various arithmetic operations like addition, subtraction, multiplication and division. Appreciate these different arithmetic operations of integers with the aid of examples. You will also learn about the properties of rational numbers

Next, you will learn about algebraic expressions and how to simplify them. Learn how to write such equations and formulae and describe the relationship between the variables. We will take you through a step-by-step process of solving equations with the aid of illustrations. In mathematics, an inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions. For example, you use it often to compare two numbers on the number line by their size. This course analyzes solving inequalities along with the different operator types in mathematics and the problem-solving applications of inequalities. Without conjunctions and disjunctions, we won't join statements logically. The material explicitly demonstrates how to use these compounds with the aid of examples. A ratio is defined as a tool used to compare the size of two or more quantities in relation to each other. Ratios allow us to measure and express quantities by making them easier to interpret. This engaging introductory course will teach you all you need to know to use ratios and proportions confidently. Don’t delay - register today!
