Easiest
1. 70 x 40
2. 70 x 100
3. 70 x 21
4. 70 x 57
Hardest

The reason I placed the numbers in this order is because 70 x 40 and 70 x 100 have zeros and therefore much easier to figure out and 70 x 21 is harder because you don’t have as many zeros, so you have to do two lots of working out. The same reason for 70x57, but they use larger numbers.
