Level 5-6 Algebra - Formulae
Now you are studying KS3 Maths you'll have come across many formulae. We use them to work out the areas of 2-dimensional shapes, the volumes of 3-dimensional shapes, certain scientific values and plenty more besides. We also find a lot of formulae in algebra.
So, what exactly are formulae? There are many different definitions but the one we like best is: 'two mathematical expressions connected by an equals sign'. Formulae tend to be remembered in one arrangement. For instance, you should recall that the formula for the area of a circle is area = πr2. This is fine if you know r but what if you are given the area and need to find r? You will need to rearrange the formula so that r is the subject. Can you master it?
This quiz allows you to dip your maths toe in the formulae waters! Take your time and read each question carefully before you choose your answers. And don't forget to read the helpful comments after each question. They can shed light on things you might have missed. Good luck!
