Mistake in calc guide 4.1

Hello all!
Calc guide 4.1, Figure 163: Setting up a formula with arguments
Am I wrong... or the formula is wrong? :slight_smile:
You could as well consider the image correct... but the formula should be with a "+" , not a "-".
Namasté :slight_smile:

The type of error that Elcico found is not uncommon in technical
documentation.

By reporting it, instead of just silently fixing it, people working on
either the same document, or a later version of it, in their target
language, are notified and can correct the error.

Whether or not it is cost effective to go back to the 3.x documentation,
to fix it, a slightly different question.
