Expressions are very important in algebra, and in maths generally. This KS3 Maths quiz deals with interpreting expressions; by this we mean applying algebra to real-life situations. It is worth remembering that the purpose of maths is to eventually be able to use it in real life!
An expression is a mathematical sentence. Mathematical sentences are numbers and symbols grouped together in such a way that they show the value of something. So, in algebra, you can think of an expression as one or a number of mathematical symbols that represent a number or quantity. Expressions can contain any number of numbers, letters and symbols. Even a single number on its own is an expression.
