Mathematical literacy

3 In doing calculations, there are maths words that we need to understand. For example, in adding 25 to 32 we might say ‘25 plus 32’ or ‘25 added to 32’ or simply ‘25 and 32’. But we can also say ‘the total of 25 and 32’ or ‘the sum of 25 and 32’. The same happens with the other calculations too – we can use different words.
