Question

Lester has a goal of cycling a total distance of 6200 metres.

His GPS tracker recorded that he had travelled 4286 metres.

What distance does he still need to cycle to reach his goal?

Worked Solution

One strategy:

Subtract thousands first, then hundreds, then the balance (as per the solution).
Distance left = 6200 – 4286
= 2200 – 286
= 2000 – 86
= 1914 metres
