Quandaries and Queries 

How do you use inequalities in your job and in your everyday life? Thank you for your time. I appreciate it.
My name is Michael and I am in ninth grade. Hi Michael, I am a mathematician and I quite often use inequalities in my job. Sometimes I teach calculus and inequalities are very important in calculus. Just this morning I answered a question from a student in calculus. The answer came down to this.
By everyday life I expect that you mean outside of my job. Inequalities in mathematics result, in large part, from an attempt to take real physical situations and construct a mathematical model. The rules we use for inequalities come from these situations. For example If M > T and T > B then M > B. If T > F then 2T > 2F.
