Calculating the Total Number of Computers

To calculate the total number of computers that should have been brought to the school, we can follow the given information step by step.

1. Initial Delivery: - Initially, 27 computers were delivered.

2. Additional Deliveries: - Then, 12 computers were delivered to two more classes, which totals 24 computers (12 * 2).

3. Remaining Delivery: - After this, 15 more computers were supposed to be delivered.

Calculation

- 27 (initial delivery) + 24 (additional deliveries) + 15 (remaining delivery) = 66

So, the total number of computers that should have been brought to the school is 66.
