Questions & Step-by-Step Solutions

What is the value of (−1)³? (2020)
  • Step 1: Understand what (−1)³ means. It means we are multiplying -1 by itself three times.
  • Step 2: Write it out: (−1)³ = (−1) × (−1) × (−1).
  • Step 3: Calculate the first two -1s: (−1) × (−1) = 1 (because a negative times a negative equals a positive).
  • Step 4: Now we have 1 × (−1).
  • Step 5: Calculate 1 × (−1) = −1 (because a positive times a negative equals a negative).
  • Step 6: Therefore, (−1)³ = −1.
