Discussion Overview

The discussion revolves around a problem related to numbering systems in digital circuits, specifically focusing on the interpretation of multiplication in different bases. Participants are seeking help with a mathematical equation and its implications in the context of digital logic.

Discussion Character

  • Homework-related
  • Mathematical reasoning
  • Debate/contested

Main Points Raised

  • One participant presents an equation derived from a multiplication problem in a certain base, stating that (x-3)(x-6) equals x^2-11x+22.
  • Another participant questions the validity of equating (x-3)(x-6) to any expression, suggesting that the solutions for x cannot be simultaneously valid.
  • A suggestion is made to express the equation in terms of an assumed base B and convert the numbers to their decimal equivalents for solving.
  • Another participant humorously asserts that if 3 * 6 equals 22, then the base must be 8, implying a playful approach to the problem.
  • There is a light-hearted comment about the nature of the problem, indicating a mix of seriousness and humor in the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the approach to solving the problem, with some emphasizing algebraic methods while others suggest a more straightforward interpretation based on base conversion. No consensus is reached on the correct method or solution.

Contextual Notes

The discussion includes assumptions about the base being used and the interpretation of numbers in different bases, which are not fully resolved. There are also varying levels of understanding and humor present among participants.

[Help] with Numbering System "Digital Circuit"

Hello Guys ..

iam having an exam on digital circuits and i try to work on some problems about numbering systems

and i found this problems but i couldn't solve it ..

i said that (x-3)(x-6)=x^2-11x+22
then i said that

x^2-9x+18=x^2-11x+22
so 2x=4 and x=2 but i didn't know what to do after that ..so please help me :))

If 3 * 6 = 22, what is the base?

And this is for a logic circuits class? Really?
 
X=3 and X=6 are not the same solution at the same time, so saying that (x-3)(x-6)=ANYTHING is not helpful.

The solution falls out of Berkeman's approach immediately, but if you want an algebraic (and more complicated) method, try this:

Express the equation you are given as a function of an assumed base B and express everything in the equation as a decimal equivalent and then solve for B. It's trivial, really, whether you start with 3 or start with 6.

And REMEMBER, expressed as a decimal number, "22-base-B" is 2*B + 2 and similarly for the 11.
 
This was the first chapter of Digital Circuits ..an Introduction for binary and other numbering systems ...this was the first section of the course :D

and if 3 * 6 = 22
then 3 * 6 = 2+2x then base = 8 :))
 
There are 10 kinds of people in the world... :smile:
 
Hahahah ..i think ..it depends on the base we are using , Berkeman :biggrin:
