What careers use inequalities everyday?

2nd level maths teachers! Its not a smart answer. But it is true.

I think quite a lot of careers do, but often we don't realise we are using them because they become quite intuitive when they are buried in real life phenomena. Think about any time you use ranges, they're pretty much the same as inequalities.

Just about every situation you involve yourself can make an inequality (nod of approval to Capuchin).
For example, I want a new plasma TV. If the amount of funds in my account is less than the amount required to purchase this new TV, I'll have to be content with my 13" portable. If greater, then I'll be a happy boy! :D
You seem a bit jaded - I would encourage you to keep plugging with it until you come to a fine understanding - it will serve you well both in school and in life. :)
