Basic maths

In this activity I had to answer 2 to 3 digit questions. I had us the column method which is just like the written algorithm. The way you use the column method is simple. For example 116 899. 9+6 in the ones column equals 15. 90+10 from the tens column equals 100. 800+100 from the hundreds column equals 900. Add 100 and 900 together it make 1,000. Add 1,000 and 15 together and it equals 1,015. I found it hard to explain how the column method worked.
