However, the answer 2 could be justified by the principle of implied multiplication.
For example, consider the problem "2/5x."

If one strictly follows the standard order of operations, the correct interpretation would be “(2/5)*(x).”

But many calculators and textbooks state that a higher value of precedence should be placed on implied multiplication than on explicit multiplication:

Because “5x” is implied to be "5*x," it gets higher priority than "2/5." In this case, "2/5x" would be interpreted as "(2)/(5*x)."

Returning to the original problem, if one utilizes the principles of implied multiplication, then “2(9+3)” gets higher precedence than the explicit “48/2"
