Introduction Sort these mathematical statements into the table shown below. Numbers have to be added in size order (e. g. largest to smallest). You should always add the ones column first. Line up all digits in place value columns neatly. Don’t forget to add any amounts that you have exchanged. If you swap the digits around when you exchange, it makes no difference. The sum is always the greatest number. Applies to addition Doesn’t apply to addition Y 5
