How to add using compensation
take the numbers 78+24
add 2 to 78 to make it 80 because it is easier to add something ending with a 0
so 80+24=104 but we added 2 on to 78
so we take away 2 from 104 which makes it 102.
This is how to use compensations.
Great work Liam! I like that you wrote what you said in the caption as it made it easier for me to follow along. Do you find compensation helpful? Do you think you could use it for larger numbers like 1673 + 123?
ReplyDeleteWell done Liam, You explained that very well. It was easy to follow with having the working out shown as well as you talking. You definately understood what you were talking about. You seemed confident and proud of your work, as you should be. Great work, keep it up. Sharron
