To determine what the timer should read when the crew begins, we need to calculate the total time they need to prepare before the play starts.
The total preparation time is the sum of:
- Time to assemble the box stage: 40 minutes
- Time to organize the sock puppets: 13 minutes
- Time to greet the children: 10 minutes
Calculating the total preparation time:
\[
40 \, \text{minutes} + 13 \, \text{minutes} + 10 \, \text{minutes} = 63 \, \text{minutes}
\]
Since the timer needs to read a negative number when they begin preparing (indicating that 63 minutes need to be accounted for before the play starts), the timer should read:
\[
-63 \, \text{minutes}
\]
Thus, the timer should read **–63 minutes** when they begin.
