Adding and Subtracting Decimals

Today I have been  adding and subtracting decimals. I was given different numbers to subtract, and I had to try my best to get the correct answer so that it would match the number sentence. As I was doing this, I found it easy because I was able to answer most of the questions. When I completed this work I managed to get 68/100 which to me was okay, since it was my first time. Next time I do this activity I will be aiming at getting 100/100.
