Teaching guide
Add and subtract two- and three-digit numbers by using place value to partition, rearrange and regroup.
Start by counting on from the larger number, then move to partitioning into tens and ones and adding each part, and finally column addition with regrouping.
Generated and checked in code, so it is correct.
Adding the tens and ones columns without carrying the regrouped ten, and always counting on from the first number rather than the larger.
