A car corporation produced 1680 fewer cars this month than last.

Write a signed number to represent this month's change in production.

yes

well, it will be either + or - right?

I need help

To represent this month's change in production as a signed number, we need to consider the direction of the change. In this case, since the corporation produced 1620 fewer cars this month than last, we can say that production decreased.

To represent a decrease or a negative change in production, we use a negative sign (-). So, the signed number to represent this month's change in production would be -1620.

To solve the problem, you should subtract the number of cars produced this month from the number produced last month. Subtracting the smaller number from the larger number will give you a negative result, indicating a decrease in production.
