Task Description: Today I was doing my maths and there was addition and subtraction in the maths that I just did and I learned how to put high numbers or small numbers together so this work is called problem solving two. So the first page that I did was with seven hundred and two hundred and thirty one and it makes nine hundred and forty four and put in the answers in the answer box then we put in the numbers in the working box and write them backwards.
