	Bases larger than ten		2009-12-14
		Nick pose la question : For numbers in bases larger than ten, what are the digits by mathematicians' conventions? I assume the first 10 are always 0-9. I know two computer science conventions (for hexadecimal (A-F case-insensitively) and for base 85 (case-sensitivity plus 23 other characters)) and as a school student I learned that base 12 uses either T and E (which confused me when I thought they stood for Eleven and Twelve) or A and B, the latter as capitals only. Clearly, these conventions are in conflict. I saw your reply in http://mathcentral.uregina.ca/QQ/database/QQ.09.99/magin1.html as accessed a few minutes ago but hope that in the 10 years since then mathematicians have arrived at a convention. Have they? Thank you. -- Nick Claude Tardif lui répond.

	Multiplying numbers in bases other than 10		2008-01-08
		Imaiya pose la question : In class we've been learning about numbers with a base other than ten. For example, base 7, base 5, and base 6. What's really stumping me is how to multiply these numbers, when they aren't a base of 10. I've had it explained to me once, but don't seem to understand it. Here are the equations, and I've listed the first few numbers for that particular base. Base 5: 0,1,2,3,4,10,11,12,13,14,20 etc... The Equation: 34 x 42 Base 9: 1,2,3,4,5,6,7,8,10,11,12,13,14, etc... The Equation: 56 x 78 If you could explain to me how to multiply numbers with any type of base, I'd really appreaciate it. Also if you could show me how to do one of the questions that I listed, that would really help me =) Thanks so much, and once again, thank you for your great site! Stephen La Rocque lui répond.

The answer is always '22'. I just can't understand why. Can you please help. Another one related to this is it: 1. Choose a three digit number ensuring the first and third digit are differnt by at least two. 2. Make the reverse three digit number and subtract the smaller one from the larger of these. 3. Take this answer and reverse it and add these two 3 digit numbers . eg: 643 - 346 = 297 297 + 792 = 1089 it doesn't matter what numbers are used, the results are alwasy the same. eg 22 or 1089 Paul Betts lui répond.

Example: N=338, but responses to questions asked in survey I'm studying equal of 24.3, 9.8, 43.8, DON'T add up to 100%.
