A car corporation produced 1020 fewer cars this month than last.
Write a signed number to represent this month's change in production.
-1020
To represent this month's change in production, we can use a negative number since the corporation produced fewer cars.
The signed number to represent this month's change in production would be -1020.
To represent the change in production for this month, we need to determine whether the number of cars produced this month increased or decreased compared to last month.
Let's assign a positive sign for an increase and a negative sign for a decrease.
Since the car corporation produced 1020 fewer cars this month than last, it means the production decreased. Therefore, we can represent this month's change in production as a negative number.
Hence, the signed number to represent this month's change in production would be -1020.
