Which two signs need to be interchanged to make the following equation correct?

{(78+70) - (6×2)} ÷ 2 = 10

Given: {(78+70) - (6×2)} ÷ 2 = 10

​$$\begin{array}{|c|c|} \hline\textbf{Operation preference wise} & \textbf{Symbol} \\\hline\text{Brackets} &[],{}, () \\ \hline \text{Orders, of} & (power), √ (root) , of \\ \hline \text{Division}& ÷ \\ \hline \text{Multiplication} & × \\ \hline \text{Addition} & + \\ \hline \text{Subtraction} & - \\\hline \end{array}$$​​

A)   + , ×

{(78 × 70) - (6 + 2)} ÷ 2 = 10 

2726 = 10 (Incorrect)

B)   - , +

{(78 - 70) + (6×2)} ÷ 2 = 10

{8 + 12} ÷ 2 = 10

20 ÷ 2 = 10

10 = 10 (Correct)

Thus, correct option is (b).
