Answer:
-7 degrees
Step-by-step explanation:
You must subtract 8 from 1.
1 - 8 =
To subtract, add the opposite. The opposite of 8 is -8. To subtract 8 from 1, we add -8 to 1.
= 1 + (-8)

Now you need to add two numbers with different signs, one positive and one negative.
Rule for adding a positive number and a negative number:
1. Find the absolute values of both numbers. Remove the negative sign: you now have 1 and 8.
2. Subtract the smaller number from the larger number. 8 - 1 = 7
3. The answer has the same sign as the number with greater absolute value. The two numbers being added are 1 and -8. The absolute values are 1 and 8, respectively. 8 is greater than 1. 8 is the greater absolute value, and it is the absolute value of -8, so the answer has the same sign as -8, so the answer is negative. We already knew the number was 7, so the answer is -7.
