To evaluate the expression '6 - 6 / 3 + 3', it is important to remember the order of operations, often summarized by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

First, we need to perform the division part of the expression:

1. Calculate '6 / 3', which equals '2'.

Now, we can rewrite the expression substituting the division result:

'6 - 2 + 3'

Next, we will perform the subtraction and addition from left to right:

2. Start with '6 - 2', which equals '4'.

3. Finally, add '3' to '4', resulting in '7'.

Thus, the overall evaluation of the expression '6 - 6 / 3 + 3' equals '7'. Hence, the correct answer is that the expression evaluates to 7.
