These worksheets focus on adding set of four integers. This can be very helpful for a progression towards multiplication mastery. How to Setup the Addition of Four Two-Digit Numbers- Adding 2 two-digit numbers is easy, but sometimes pupils in grade 1 and 2 face difficulty adding multiple two-digit numbers. Here is a step by step guide on how you can add 4 two-digit numbers easily. Let's say you have a problem in which you have to add the numbers 23, 42, 36, and 55. To make things easier, we'll put all the numbers in a vertical fashion.

23+ 42 +36 + 55 =

To solve this, we will use a method called the break apart method in which we will break all these numbers into their expanded forms such as:

20 + 3, 40 + 2, 30 + 6, +50 + 5

Now, as you can see, these numbers have been expanded into simpler forms, making it easier for them to be added. Now let's add them

20 + 3, 40 + 2, 30 + 6, +50 + 5    or    140 + 16 =

Now, let's add 140 + 16, which makes up 156. Break apart method is one of the simplest addition methods you can use to make the addition of multiple numbers simpler and easier.
