Adding 10 to a number is almost as easy as adding 0.
Just add 1 to the Tens place.
Then write the same number in the Ones place.
Let's look at some more examples:
2 + 10 = 12
3 + 10 = 13
4 + 10 = 14
5 + 10 = 15
6 + 10 = 16
7 + 10 = 17
8 + 10 = 18
9 + 10 = 19
10 + 10 = 20
Great job learning to add 10.
