To evaluate the expression \( f - 5 \) when \( f = 12 \), you simply substitute the value of \( f \) into the expression. So, it's \( 12 - 5 = 7 \). Boom! You've got yourself a neat whole number! Keep in mind that evaluating expressions is like solving a puzzle. Just remember to replace the variable with the given value, follow the order of operations if there are multiple steps, and watch out for common pitfalls like forgetting negative signs or performing the operations out of order. Happy evaluating!
