Discount, then tax, in order

Choose a marked price, a discount and a tax. The console applies them in the fixed order and reports the net change against the marked price. Try equal percentages — an 18% discount with an 18% tax leaves you below the label, not level with it, for the same reason a markup and an equal discount never cancel.

The final stat is the net change against the marked price. It goes positive or negative depending on which percentage is larger, and it is never their simple difference.
