I am in eleventh grade and I am about to enter a mathematics competition thursday...I would really appreciate it if someone would "quiz" me or ask me questions and critique my answers..I would really appreciate it!...also I know a fair amount of mathematics...but one thing that alludes me is what a unit digit is...if someoen could explain the concept as well as an application/question typical of that topic...thanks so much!

With all due respect, no offence intended or implied, I find those two statements incredible.
The last time I checked the 11th grade is not in the middle school.
Somewhere before middle you should have learned about the unit digit.
Skip the competition.

units
any time you here the word "unit" in mathematics, you're dealing with 1. The "unit digit" of a decimal number is whatever digit is situated in what you used to call the "one's place". For example, the unit digit of 356.798 is 6.

haha...its ok
YOu are right that is sad that I did not know that but I am actually pretty knowledgable...I completed calc AB in eight grade...I just never learned what it meant...trust me I am beyond ready...I was just wondering =D

Good Grief! Does that ever speak to a point that I have been on a ‘soap box’ about for about thirty years. I have opposed the so-called “AP-Calculus” in U.S. secondary schools. My opposition has nothing to do with a student’s ability to learn the material, but rather it has to do with the ability of availability of the teachers. Now I speak from a great deal of experience. I have taught in many “teacher training courses for AP-calculus sessions”. But I gave up. Only 1 in 20 were able to really grasp the basic notation of calculus. What an absolute shame that someone is allowed to do the Calculus AB course and complete it without knowing about a unit digit.

Come on
You know how certain math teachings can be esoteric to certain areas..for example I told some kids in my school to solve two simulataneous equations they'd be dumbfounded but if I asked them to solve two systems of equations they'd be ready and raring...I knew what a unit digit was...but by the different name of unit number..I am sure I should have made the connection but it didnt

I happen to know what MathStud28 is talking about. When I was in younger grades I used to help out the 12th graders with their Calculus. I was able to do the problems, usually easily, the only problem I had sometimes was to understand some terms which they used in the problems. Because when you study math by yourself there are just some words you never seen before.

Thank
you are right once again
