Step-by-step explanation:

On the last page, we looked at some mathematical expressions. Expressions are useful, since they can help you keep track of the amounts you're adding.

Any addition problem can be turned into a written expression. For instance, say that you planned to have three friends come over for dinner. At the last minute, you invite two more. To get the total number of friends who are coming to your house, you might write an expression like this:

3 + 2

The expression is just another way of describing the situation: three friends plus two more are coming over for dinner.

Try This!

Write these situations as mathematical expressions. Don't solve the problems yet — simply set them up.

You ate three pieces of pizza for lunch. At dinner, you ate two more:

You already waited five minutes to see the doctor. The nurse tells you to wait five more minutes:

Your coat has four buttons on the right side and three buttons on the left side:

Solving Problems

Now that you know how to write addition problems, let's solve some. When you're just getting started, you might find it easier to use counting to solve problems.

With that problem, you were able to count the objects you were adding. In real life, some people like to count with their fingers. Other people use small objects, like buttons or pennies. Others might make small marks on a piece of paper. When you're learning to add, it's OK to count! The more you practice, the easier it will get to add without counting.
