Explanation:

- Original Equation: 14 + 4 ÷ 5 - 18 × 2 = 25

- Goal: Make it correct by swapping two signs.

Options Analysis:

1. Swap × and +

- New Equation: 14 × 4 ÷ 5 - 18 + 2

- Calculation: 14 × 4 = 56, 56 ÷ 5 = 11.2, 11.2 - 18 = -6.8, -6.8 + 2 = -4.8

- Not equal to 25.

2. Swap ÷ and +

- New Equation: 14 ÷ 4 + 5 - 18 × 2

- Calculation: 14 ÷ 4 = 3.5, 3.5 + 5 = 8.5, 8.5 - 18 = -9.5, -9.5 × 2 = -19

- Not equal to 25.

3. Swap × and -

- New Equation: 14 + 4 ÷ 5 × 18 - 2

- Calculation: 4 ÷ 5 = 0.8, 0.8 × 18 = 14.4, 14 + 14.4 = 28.4, 28.4 - 2 = 26.4

- Not equal to 25.

4. Swap ÷ and ×

- New Equation: 14 + 4 × 5 - 18 ÷ 2

- Calculation: 4 × 5 = 20, 14 + 20 = 34, 18 ÷ 2 = 9, 34 - 9 = 25

- Equal to 25.
