What is the value of \( 7 \times 8 - 9 \)?

To find the value of ( 7 \times 8 - 9 ), begin by calculating ( 7 \times 8 ).

When you multiply ( 7 ) by ( 8 ), you get ( 56 ). Next, subtract ( 9 ) from this result. So, you perform the operation:

[

56 - 9 = 47

]

It appears there was a miscalculation in arriving at ( 54 ) as the answer. The correct conclusion shows that the final result is ( 47 ), which differs from all the choices given. As observed, ( 54 ) is close to ( 56 ) but does not represent the correct outcome of the calculations. Always ensure to carry out operations step by step and verify each stage to avoid errors.

Thus, the correct computation yields ( 47 ), highlighting an essential aspect of arithmetic: careful operation management leads to valid results.
