Explain how you dind the sum of 46+7

You add 7 and 6 to get 13, and then add the 1 from 13 to the 4 in 40, and the 3 from 13 you add to the 0 in 40 to get
53.

If set up as: 46
+ 7

First add 6+7 to equal 13. Since the number is over 10, add a 1 to the first column. Add 4 + 1 to equal 5. The answer is 53

Hope this helps!! :)
