Final answer:
In mathematics, signed numbers represent weight changes or production differences through + and - symbols.
Explanation:
A signed number represents the weight change appropriately, depending on the situation:
- (a) If an animal gained 6 pounds, the signed number would be +6.
- (b) If a car corporation produced 1900 fewer cars this month than last, the signed number would be -1900.
