I'm working on a math calculation in GDScript and I'm confused about the result I'm getting. I'm using two variables, `heal_amount` set to -1 and `_quality` set to 3. Here's the code snippet I'm working with:
```python
var _amount = int( (float(heal_amount)) * ((float(_quality) + 1.0) / 4.0) + 1.0)
```
When I print out some debug statements, I see this output:
```
-1.0 * ((3.0 + 1) / 4) + 1
-1.0 * 2.0
-2
0
0
```
I'm not sure how -1.0 multiplied by 2.0 results in 0. Can anyone help me understand what's going wrong? I'm using Godot 4.4.1 stable from Steam.

No worries, it happens to the best of us! You're right about the parentheses—a small change like that can significantly affect how your calculations are performed. Make sure to check the parenthesis placement next time!
Looks like you figured it out! It can be easy to lose track of them when you're deep in coding for hours. Remember to take breaks and come back with a fresh mind!
Your issue might just be a lack of parentheses. You originally had:
```
-1.0 * ((3.0 + 1) / 4) + 1
```
If you meant to do something like this:
```
-1.0 * (((3.0 + 1) / 4) + 1)
```
That would change your calculations a bit and lead to a different outcome.
It looks like you've got the right idea, but you might be mixing up the order of operations. From your calculations:
```
-1.0 * ((3.0 + 1) / 4) + 1
-1.0 * (4.0 / 4) + 1
-1.0 * 1.0 + 1
-1.0 + 1
0
```
So actually, -1.0 times 1.0 does equal -1.0, and then when you add 1 to it you get 0. It seems correct so far!
Haha, we all have those moments. Don't be too hard on yourself—coding for long hours can make you overlook simple details! Just remember: parentheses are your friends. Sleep is important too!
