Problem Solving: Finding the Number of Pencils

To solve this problem, we can follow the steps provided in the question.

1. Initial Number of Pencils: The box initially contained 12 pencils. 2. Pencils Taken Out: Initially, 5 pencils were taken out from the box. 3. Pencils Put Back In: After taking out the pencils, 3 pencils were put back into the box.

Now, let's calculate the total number of pencils in the box after these operations.

Calculation

To find the total number of pencils in the box after taking out and putting back in, we can use the following formula: Total number of pencils = (Initial number of pencils - Pencils taken out) + Pencils put back in

Substituting the given values: Total number of pencils = (12 - 5) + 3 Total number of pencils = 7 + 3 Total number of pencils = 10

So, after taking out 5 pencils and putting back 3 pencils, there are 10 pencils in the box.

This calculation is based on the given information and the basic principles of arithmetic.
