Here’s a part of why this takes so long…
Learning that you can’t use negative numbers in math expressions natively (without a work around).
When you just want to write a simple equation and it’s an error and you spend 10 minutes (multiply by 3 kids around the house = 1 hr).

What?? I’ve never used UE5 but that sounds so weird — no native negative numbers in math expressions??
