If you feel bad for feeling like you're getting belittled for struggling with the math mechanic
Just remember, the majority's brains stop working when it comes to Sweep the Leg. :P

Basically, sure this mechanic might be simple to some people but that doesn't apply for everyone. There will be some who struggle with this, but I'm sure that there are people who always have at least one mechanic they really struggle with. I get that it's pretty hard, but I don't think it means the mechanic should be taken out.
