Which two signs should be interchanged to make the given equation correct? 2 - 8 ÷ 4 = 6 x 3 + 18

x and -  = and + x and + + and -

= and +

In the equation: 2 - 8 ÷ 4 = 6 x 3 + 18, if we interchange = and +, the new equation is: 2 - 8 ÷ 4 + 6 x 3 = 18 Using BODMAS rule,    2 - 8 ÷ 4 + 6 x 3 = 18 ⇒ 2 - 2 + 18 = 18          LHS = RHS Thus, the above change makes the equation correct.
