To find the “sum” of something means you need to add the numbers together. A lot of people have trouble remembering which operation to do to find the sum.
If you need help with adding the numbers, there are a variety of different methods you can use to get the correct answer. I always like to help students find the method that works best for them.
Here’s one way that a lot of kids find easy.
Add the 10 + 20 = 30
Then add the 2 + 4 = 6
Add the 30 + 6 = 36
That’s it!
Easy Peasy!
With a some practice, you can probably learn how to do that in your head!
Look at how smart you are!!
