Can you round the numbers up or down to help?
Can you 'picture' the calculation in your head somehow?
Perhaps you can use some number facts that you know well to help?
Does your answer sound reasonable?
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the
NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to
embed rich mathematical tasks into everyday classroom practice. More information on many of our other activities
can be found here.
