Strategy for Addition

This picture on the top is a strategy for addition. I normally use the normal way when you put the two numbers vertically. This picture on the top is a strategy when you break up the numbers into tens place and the ones place. 

Now, you got the answer for the tens place and the ones place. Then you add the tens place and the ones place answers together. Then the answer will come out ( if your addition is correct ).

Some people maybe think that this strategy is useful, but some people might think that the vertical way is easier than this strategy.

Hajime 🙂
