Not sure why it's like that in the Engine. It's the same in the Animations. If it's "up", then Y gets subtracted. I suspect whomever programmed it has never viewed an X,Y Axis graph.

It works the same way as an image in an image editor does: the top left pixel/tile is 0, 0. This is more common than the Y axis starting at the bottom, which is mainly a maths thing.

When a program counts lines of a screen or an image from bottom to top, it's the true nightmare. Computers are a big pile of digital math, that doesn't mean pixels have to resemble the top-right graph-quadrant.
Graphs and 3D-environments need a center-point to work, screens and images on the other hand just begin to exist at 0|0.

probably the same guy 10.000 years ago who decided to write left to right, top to bottom.

Maybe he lived on the top floor of a building?

As Trihan said, this is standard for everything that has to do with electronic displays.

You could use the .abs function to always get positive numbers,
or you insert two conditions:
if X is less than 0 than do X*(-1)
if Y is less than 0 than do Y*(-1)
than X + Y = Distance.
Edit: Your Problem would still remain even if it would be vice versa.

@ATT_Turan @Trihan @AkiraKotatsuhime Very interesting. I figured that was the case.
@Bex I've actually already fixed my problem. Here's an image showing how:
It allows even combinations like (3X, -3Y) to equal -6 Distance and vice versa instead of just cancelling out to zero.

If you don't mind dipping your toe in script a bit, you can do this a lot more easily by using the deltaXFrom and deltaYFrom functions.

Not gonna lie, never used any other engine that worked this way. Unity is y + 1 == up, same for GameMaker.
Didn't know image editors used inverted axes too.

If you are a fan of TRPGs like Fire Emblem, take a moment to help me by filling out this:
The concept art for the sprite of Senary, a major character in my upcoming (as-of-yet-unnamed) project. She is known as the Timelord because she can "stop time" by making eye contact with a person; Paralyzing them for a short period of time through a type of hypnosis. Tell me what you think about her. I'm thinking of changing the color of her coat.
