2•(-23•45)

Let's solve the expression step by step: \[ 2 \cdot (-23 \cdot 45) \] First, calculate \( -23 \cdot 45 \): \[ -23 \times 45 = -23 \times (40 + 5) = -23 \times 40 - 23 \times 5 = -920 - 115 = -1035 \] Now, multiply this result by 2: \[ 2 \times -1035 = -2070 \] **Final answer: \(\boxed{-2070}\)**
