I am rude.? screw off, and die. Look at the rude comment beore mine you \$%^\$?

I will not be back. You people are &\$&%

I had already figured it out geniuses, but before i could post i was insulted. Thanks for being an \$^%& Mr.moderator.

Just like an &\$&%

No  need to figure it out.It is stated clearly in my last post. Thanks for the advice. You might benefit from reading your lecture notes also.

Hey! I look like you now.

## #3 Re: Help Me ! » Is the system a group? » 2007-11-15 16:35:38

The official answer is C. Now to figure out why. I'll be back.

## #7 Re: Help Me ! » Is the system a group? » 2007-11-15 04:45:13

But how does that account for the rest of the properties?

You forgot 78.

## #9 Re: Help Me ! » solutions ofr x congruency mod (6) » 2007-11-15 00:16:10

I see what your saying. it makes sense, but what is the answer.

Aha! The difference between 5 and the digits in answer D all divide by mod 6 with no remainder. Thus D is the answer because the other options include numbers that do not divide evenly.That is, they have remainders when divided by 6.

One integer n is said to be divisible by another integer m if m divides n with no remainder. So 14 is divisible by 7 but 15 is not.

Two integers m and n are said to be congruent modulo N (N also an integer) if their difference is divisible by N.

I now realize that there is no zero. You would need a zero for Identity I guess, but Jane which do you think is the answer and why?

Wow! Thank you jane. You are always so faithful to math. is that a picture of you?Wow!

Tell me about it. Why the devil must they try to trick the student?

## #13 Re: Help Me ! » solutions ofr x congruency mod (6) » 2007-11-14 20:43:26

Sorry . the answer is D because all three numbers leave the exact remainder of 5 when divided by the mod-6.They all leave 5 which is equal to the 5 shown.

At least that is what all the other forums say, but somehow i am not convinced. You may be right.

I've saved this to email.i'll be back with an explanation and the verified answer.

## #14 Re: Help Me ! » Is the system a group? » 2007-11-14 16:56:26

But as far as identity, I guess not cause you'd need a one or a zero. I am probably wrong.

## #15 Re: Help Me ! » When applied to the integers, multiplication is distributive over divi » 2007-11-14 16:53:42

Hmm. Ehhe! That's great. However, I think as a general rule the answer would be no. However, I believe multiplication is distributive over addition:

a · (b + c) = (a · b) + (a · c)

a + (b · c) = (a + b) · (a + c)

Solve the problem.
Decide whether the system is a group. If it is not a group, identify which of the following properties it fails to satisfy: closure, associativity, identity, inverse. Even integers; multiplication

a.     Not a group; identity, inverse, associative           b.     Not a group; closure           c.     Not a group; identity, inverse           d.     Group

Is this true:

When applied to the integers, multiplication is distributive over division.

## #22 Re: Help Me ! » Find the number succeeding and preceeding EOE base 12 » 2007-11-14 08:51:14

You know the original question is probably a program glitch in "My MathLab," but it had me busting my brain for hours. Thanks any way. Particular thanks for the interger sequence.

Does the sequence work like this for other alphanumeric base numbers as well?

I mean I had a test where they were clearly asking me about what numbers preceded and proceeded certain base numbers that included alphanumeric digits, but how the hell am I suppose to know this whithout a chart or something. It's almost like there is a rule or something as to where the letters begin to appear in certain base number systems????????

Thanks again.

## #23 Re: Help Me ! » Find the number succeeding and preceeding EOE base 12 » 2007-11-13 17:14:29

I swear I am asking the same thing. What the hell! It's in my math lab and I am so confused now. I was doing just fine, and now their asking me some weirdness.

I do not want to disregard the question , but as a sidenote, can you write me a sequence of 30 integers in base 12. I have a hard time understanding how the letters develop.

Thanks.

Hey I know how to convert from one base to the other, but how in the world do I figure out what goes before and after EOE base 12?  I am so confused.

Wow1 Thanks.
