Simplifying 12(9)÷(3)312(-9) \div (-3)^3

To simplify an expression involving exponents, multiplication, and division with integers, follow the order of operations by resolving exponents prior to performing multiplication or division:

  1. Exponents first: Evaluate (3)3=(3)(3)(3)=27(-3)^3 = (-3)(-3)(-3) = -27. Since the base is negative and the exponent is odd, the result is negative. The expression becomes 12(9)÷(27)12(-9) \div (-27).
  2. Multiply: Perform multiplication moving from left to right. Compute 12(9)=10812(-9) = -108 (multiplying numbers with different signs results in a negative product). The expression becomes 108÷(27)-108 \div (-27).
  3. Divide: Finally, compute 108÷(27)=4-108 \div (-27) = 4 (dividing numbers with the same signs yields a positive quotient).

The final result is 44. This example reinforces that exponents are resolved first, followed by multiplication and division executed sequentially from left to right.
