Answer:
The sum −3 is an indication that Sally is 3 feet below her initial position.
Step-by-step explanation:
Represent the distances going up (ascend) as positive and distances going down (descend) as negative so that the sum is:
224 + (-131) + 67+ (-163)
Add by using the commutative property:
224 + 67 + (-131) + (-163) = 291
The sum −3 is an indication that Sally is 3 feet below her initial position.
