Which two signs should be interchanged to make the given equation correct? 306 ÷ 17 + 4 − 50 × 8 = 30
+ and ×
The correct answer is + and ×.
These also have equal precedence and should be performed from left to right as they appear. When you interchange signs, you create a new expression. You must apply BODMAS/PEMDAS to this new expression to see if it evaluates to the target value (in this case, 30). For example, in the expression $18 \times 4 - 50 + 8$, Multiplication ($18 \times 4$) is done before Subtraction ($72 - 50$) and Addition ($22 + 8$) according to the rules.
