Writing numerical expressions, step by step
"Add 8 and 7, then multiply by 2" is 2 × (8 + 7), and the bracket is the whole answer.
The question
Which expression is 3 times as large as 215 + 159?
Read it in order, then say which way round
= a number
adding
3 × (215 + 159)
- The phrase is "3 times as large as 215 + 159". The letter null is the number nobody has told us; everything else in the phrase says what to do to it.
- The words say we are adding.
- "more than" makes 215 bigger, so 215 is what is added to.
