Explanation:

- We start with the equation: $45 \times 10 - 125 \div 25 + 5 = 30$ .

- Option 1: Swap '÷' and '-'. The equation: $45 \times 10 + 125 \times 25 - 5$ becomes incorrect, as it gives a large number.

- Option 2: Swap '×' and '+'. The new equation: $45 + 10 - 125 \div 25 \times 5$ . Calculate as: $45 + 10 - 5 \times 5 = 50 - 25 = 25$ , which is not equal to 30.

- Option 3: Swap '×' and '-'. The equation: $45 - 10 + 125 \div 25 \times 5$ . Calculate: $35 + 25 = 60$ , which is not correct.

- Option 4: Swap '-' and '+'. The equation becomes: $45 \times 10 + 125 \div 25 - 5$ . Calculate as: $450 + 5 - 5 = 450$ , incorrect.

Answer:

- None of the options seems to make the equation correct, upon reevaluation of computational steps.
