Answer:
8+7
Step-by-step explanation:
Absolute value is when you calculate how far away the number is from zero.
Since 8 is 8 spaces away from zero, then the absolute value of 8 is 8.
Since -7 is 7 spaces away from zero, then the absolute value of -7 is 7.
So, in conclusion, an equivalent expression can be 8+7
Answer:
