Formulas and Equations (F)

Welcome to our GCSE Maths Formulas and Equations quiz. Beyond just numbers and equations, we believe in fostering a curiosity for the world around us, even within the realm of mathematics. So here is a video short. Sit back, absorb the knowledge, and let's make maths revision an enlightening journey together.

A formula is a special type of equation that shows how two or more variables (letters) are related. You will already be familiar with some, like the formula for the area of a rectangle. If you know the length and width, you can use the formula to calculate the area. A useful thing about formulas is that you can rearrange them to work out the value of another variable. So if you know the area of a rectangle and its width, you can calculate the length. Test your skills in using and rearranging formulae in this GCSE Maths quiz.

You have to know how to SUBSTITUTE a value into a formula – you do this when you are told what value a variable has. Every time the letter appears in the formula, replace it with the number, remembering to keep the same relationships such as multiplying or adding.
