If n = 2 + 21/3 + 22/3, then find the value of n3 -6n2 + 6n. (Not a homework problem) 106.215.118.66 ( talk) 06:38, 28 January 2014 (UTC)
In what way do you use "between" in context with number intervals? Is a number "between 1 and 10" the same as "from 1 to 10", or different in the way that it does exclude 1 and 10? Or is this expression used ambiguously? -- KnightMove ( talk) 11:29, 28 January 2014 (UTC)
It would have been better to explain the background: I'm well informed about the formal ways to write in mathematics. The reason for my question was a mathematical puzzle for laymen which, however, was not carefully worded, with many ambiguities, and depending on those the puzzle had many different interpretations. I just wanted to check this specific aspect. Thanks for your answers. -- KnightMove ( talk) 08:56, 29 January 2014 (UTC)
Any Internet sites where I can see pictures of the following triangles:
Pascal's triangle, with each number replaced by a colored cell where the color depends on the remainder the number leaves when divided by n. Examples:
And so on. Georgia guy ( talk) 21:05, 28 January 2014 (UTC)
