Answer 2

Answer:

1) Horizontal addition is a summation strategy that breaks down the summands by taking note of the positional value and continuing with the addition.

2) When writing down sums, separate the numbers into ones, tens, hundreds and thousands. List the numbers in a column and always start adding with the ones first.

3) It also means that they are not learning to add and subtract multiples of 10 or 100 (for example: 30 + 90, 120 - 50 etc).

4) The standard algorithm for two-digit subtraction with regrouping is introduced.
