Question

Identify whether each value is negative or positive.

Answer 1

Answer:

Step-by-step explanation:

This is all about odd or even minus signs.

• An odd number of minus signs in term gives a minus answer
• An even number of minus signs in term gives a plus answer

-2^2  the power does NOT affect how the answer when there are no brackets around the 2. the answer you want is minus

(-2)^2 This is an entirely different question from the one above.  The power (^2) affects both the 2 and the minus. There are now 2 minus's. The answer is plus.

(-3)^3 means there are 3 minus signs to be multiplied together. Three is an odd number. The answer is minus.

12 is even the brackets includes the sign. The answer is +

171 is minus because 171 is odd.
