÷ and +

÷ and ×

× and −

× and +

Let's analyze the options one by one.

- Original Equation: 20 + 5 × 3 ÷ 3 - 1 = 14

- Option 1: If we interchange ÷ and +, the equation becomes 20 ÷ 5 × 3 + 3 - 1.

- Simplifying: 4 × 3 + 3 - 1 = 14

- This calculation yields 14.

- This option works.

- Option 2: If we interchange ÷ and ×, the equation becomes 20 + 5 ÷ 3 × 3 - 1.

- Simplifying: 20 + 5 - 1 ? 14

- This doesn't work.

- Option 3: Interchanging × and - gives 20 + 5 - 3 ÷ 3 × 1.

- Calculating: 20 + 5 - 1 ? 14

- This doesn't solve the equation.

- Option 4: Interchanging × and + gives 20 × 5 + 3 ÷ 3 - 1.

- Calculating: 100 + 1 - 1 ? 14

- This also doesn’t work.
