What is the maximum age someone can start college in the USA?
Do you have to take maths in college?
When do you decide what you want to major in?

I’m not aware of a maximum age, and I know of people who have gone to college for the first time as grandparents. That said, the vast majority of first years will be in the 18-20 range, same as in the UK.

Different colleges/universities have different policies. Most require at least one class in something ‘quantitative’, but there is usually a wide range of options that are not particularly math-y. You can choose not to apply to colleges that require an actual math class (and you can find that info online- one way is to look up the graduation requirements).

It varies a bit, depending on the college/university, but by generally by the middle/end of the second year. You have to apply straight in to some courses (engineering, for example), and some are best started early (usually sciences) but as you want to avoid math I’m guessing that you aren’t looking at either of those fields!

Some if the math classes, like Math and money , Math and citizenship (about elections etc), or Geometry and art, are actually pretty cool.
While most people in university are 18-23, some universities are especially hospitable to Veterans and thus have older students. omen’s college’s also have programs for women with children who interrupted their education for any reason.
Any specific reason why you’re asking?

In the first year of USA university, you usually have to take a maths class if you had not fulfilled general course requirements already. Check individual university sites for this, because this can vary. For example, since I live in New York, if you get mastery on all Regents exams, then you don’t have to take that class in university (only New York universities though).

In terms of major, I know people who decided to go to university “Undecided,” however after the 1 year you should, if not have to, decide what you want to major in.

However, the math requirement for many majors that don’t require math usually is incredibly simple (and you may just have to fulfill a “logical reasoning” requirement instead).
