Calculation of Books Issued on Each Day

To calculate the number of books issued on the third day, we need to add up the number of books issued on the first and second days and then subtract the number of books issued on the third day.

Let's break down the information given:

- First day: 12 books issued - Second day: 20 books more than the first day - Third day: 10 books less than the second day

To find the number of books issued on the third day, we can use the following calculation:

Number of books issued on the third day = (Number of books issued on the first day) + (Number of books issued on the second day) - (Number of books issued on the third day)

Let's substitute the given values into the equation:

Number of books issued on the third day = 12 + (12 + 20) - (12 + 20 - 10)

Simplifying the equation:

Number of books issued on the third day = 12 + 32 - 22

Number of books issued on the third day = 44 - 22

Number of books issued on the third day = 22

Therefore, 22 books were issued on the third day.
