    2x still means 2 * x.

    x is still multiplied last. There’s not a rule for implied multiplication shorthand preceding operations to the left. You still need to wrap 2x in parentheses if you want the operation to occur first.

    This isn’t like a polynomial like ax^2 + bx + c as division is done between 6 and 2 before multiplication with x. Typically you wouldn’t see such an equation (which is intended to trick you) as normally addition or subtraction would occur like in a polynomial or another variable equation (such as a linear graph), which would be done after the exponents, multiplication, and division with the variables are calculated. In the instance you wrote, it should be written as (6/2)x, or 3x, to avoid obscuring the equation. Though you intended for 6/(2x), or 3/x.

    And no worries, comrade, I’m just meaning to help since I am good at math and like helping people (I don’t mean this in an egotistical way). I’m not taking offense, and I am not meaning to offend anyone.
