Show answer & explanation
Correct answer: B
Correct combination: − , ÷ , + , × , =
This yields the equation: 45 − 44 ÷ 22 + 17 × 89 = 1556
Step 1: Perform division: 44 ÷ 22 = 2.
Step 2: Perform multiplication: 17 × 89 = 1513.
Step 3: Now do addition and subtraction left to right: 45 − 2 + 1513 = 43 + 1513 = 1556.
Conclusion: The left-hand side evaluates to 1556, so the sequence − , ÷ , + , × , = correctly balances the equation.
