Calculating the Change in the Number of Notebooks on the Table

To calculate the change in the number of notebooks on the table, we can follow these steps:

1. Initial Number of Notebooks: 8 notebooks were initially taken from the table. 2. Additional Notebooks: Then, 9 more notebooks were taken from the table.

Calculation

To find out how many notebooks are left on the table, we can calculate the change using the following formula: Remaining notebooks = Initial number of notebooks - Total notebooks taken

Remaining notebooks = 8 - (8 + 9)

Remaining notebooks = 8 - 17

Remaining notebooks = -9

Conclusion

The number of notebooks on the table decreased by 9.
