5+7+6*3*9

To solve the expression \( 5 + 7 + 6 \times 3 \times 9 \), you need to follow the order of operations (PEMDAS/BODMAS), which dictates that you perform multiplication before addition.

1. First, calculate the multiplication: \[ 6 \times 3 = 18 \] Then, multiply that result by 9: \[ 18 \times 9 = 162 \]

2. Now substitute this back into the expression: \[ 5 + 7 + 162 \]

3. Now proceed with the addition: \[ 5 + 7 = 12 \] \[ 12 + 162 = 174 \]

So, the final answer is \( 174 \).
