Which two signs should be interchanged to make the following equation correct? 139 + 40 ÷ 5 - 168 × 3 = 283
÷ and ×
We need to interchange the signs in the equation to make it correct. If we change the '+' between 139 and 40, and the '×' between 40 and 5, the equation becomes 139 × 40 – 5 = 168 × 3 = 283. Thus, the correct answer is option 3: + and ×.
