This page is an excellent illustration of how knowing ‘tables’ and understanding place value can make other maths much simpler. These questions are all multiplying multiples of ten by a single digit.
If you know that 7 x 8 = 56 then 70 x 8 can be done ‘in your head’ very quickly.
probably the hardest questions on this sheet are those set out like this:
490 x 7 = ??
The best way to approach this is to ask what times 7 makes 49? and work from there.
