Question

Describe a real-world situation that models the multiplication expression 20(-1).

Answer 1

Basically you can write taking from something or using something 20 times. Here are three examples.

• You borrowed 1 dollar from someone 20 times.
• You descend 1 meter at a time (like a submarine).
• There are 20 candies in the jar. Each day you eat 1 candy.
