Maths, language, driving, etc. Many times we don't roll against them, but we still have them. If we don't, then we can't do them. You need a computer hacker to know you need a laser comms expert. You need to be able to speak a language to speak a language (usually). You need to be able to do basic maths to basic maths.
As opposed to a system that - for instance - has you merely rolling under an attribute number that's marginally related to a skill you've never had a drop of training in.
Then the GM doesn't let you roll for it, if you haven't had a drop of training. If that really matters.
Same goes for skills - I don't think learning basic maths in primary school has given you a drop of training in the ability to count shots during combat, either.
In either case, attribute or skill, the GM decides if what your doing can be done. The skill doesn't tell you what you can do - it just sits there in case the GM wants to make you roll on it. He could just as easily want to make you roll on an attribute.
To be clear, you don't need basic maths to do what you think is involved in basic maths. What you need is a GM who thinks your character could do what you think is involved in basic maths. That's very different from actually needing the skill to do something.
