Insert brackets to make the following true: 5+3×4-2=30. Also, (12×8)−22

Step 1: Analyze the given expression and target value. The expression is 5+3 × 4−2. We need to insert brackets to make the result 30. Step 2: Try different placements of brackets and apply the BODMAS/PEMDAS rule. Let's try placing brackets around 5+3: (5+3) × 4 − 2 First, evaluate the expression inside the brackets: 8 × 4 − 2 Next, perform the multiplication: 32 − 2 Finally, perform the subtraction: 30 This matches the target value. The correct placement of brackets is (5+3) × 4 − 2 = 30.

Answer

(5+3) \times 4 - 2 = 30

Step-by-step solution

2 steps

Analyze the given expression and target value.
The expression is $5+3 \times 4-2$ . We need to insert brackets to make the result 30.
Try different placements of brackets and apply the BODMAS/PEMDAS rule.
Let's try placing brackets around $5+3$ :
$(5+3) \times 4 - 2$
First, evaluate the expression inside the brackets:
$8 \times 4 - 2$
Next, perform the multiplication:
$32 - 2$
Finally, perform the subtraction:
$30$
This matches the target value.

The correct placement of brackets is $(5+3) \times 4 - 2 = 30$ .
