Fill in the bank with \( \langle,>,=\operatorname{sign} \)

  • A. \( (-3)+(-6)--(-3)-(-6) \)
  • B. (-21)-(-10)
  • C. 45-(-11)
  • D. (-25)-(-42)

Step-by-step solution

The expression simplifies as follows: (-3) + (-6) = -9; subtracting (-3) gives +3, so -9 + 3 = -6; subtracting (-6) gives +6, so -6 + 6 = 0. Options B, C, D evaluate to -11, 56, and 17 respectively, none equal to 0. Thus A is correct.
