SWF addition and subtraction with Jakob

1 comment:

  1. Great work Zak solving a subtraction question and a stacked addition question using SWF. You wrote good questions, however it doesn't sound like the population of NZ is very big in the year 2456! Did you want the numbers to be that small? remember the population of Christchurch a the moment is around 370,000 people.
