ADDITION STORIES (Word Problems)

Many situations around us require adding numbers.

We may have to add the amounts mentioned in a bill for purchases made

in a market.

This helps us to check, the total is correct or not.

Addition may or may not involve regrouping (carry over).

Now we will examine a few such situations in the following examples.

Example 3: 35775 children visited a fun park in January and 52012

children visited it in February. How many children
visited the fun park in these two months?

Solution: TTh Th H T O

Number of children who visited in January 3 5 7 7 5

Number of children who visited in February + 5 2 0 1 2

8 7 7 8 7

87787 children visited the fun park in January and February.
