Introduction to Equations and Inequalities

Equations are widely used to describe the world around us. In science equations are used to describe everything from how a ball rolls down a slope to how the planets move around the sun.

In this tutorial we will explore different types of equations as well as looking at how these can be used to solve problems in the real world. We will also look at linear inequalities.

Did You Know?

The first use of an “equals” sign from The Whetstone of Witte by Robert Recorde \(1557\). This equation represents \(14x + 15 = 71\). Recorde is also responsible for introducing the pre-existing “plus” sign (+) to the English-speaking world.
