7*12:21-51

Answer

To solve the expression \( 7 \times 12 \div 21 - 51 \), you should follow the order of operations (PEMDAS/BODMAS):

First, calculate \( 7 \times 12 \): \[ 7 \times 12 = 84 \]
Next, divide by 21: \[ 84 \div 21 = 4 \]
Finally, subtract 51: \[ 4 - 51 = -47 \]

So, the result of the expression \( 7 \times 12 \div 21 - 51 \) is \(-47\).

Question 2

7*12:21-51

Answer

To solve the expression \( 7 \times 12 \div 21 - 51 \), you should follow the order of operations (PEMDAS/BODMAS): 1. First, calculate \( 7 \times 12 \): \[ 7 \times 12 = 84 \] 2. Next, divide by 21: \[ 84 \div 21 = 4 \] 3. Finally, subtract 51: \[ 4 - 51 = -47 \] So, the result of the expression \( 7 \times 12 \div 21 - 51 \) is \(-47\).
