 Mar 8 revised What is a square root? Fixed restating the same thing two different ways, to be what the author intended. Mar 8 suggested approved edit on What is a square root? Jan 5 comment Optimization-like question "while differing from their previous values as little as possible". There are more than one way to minimize three values.. You need to decide which norm you want L1 minimizes the sum of the three differences, L2 minimizes the sum of their squares, and Linfinity minimizes the maximum difference. Suppose that their values could be changed like any of the follow to meet N: (0,0,+2),(+0.5,+0.5,+1.1),(+1,+1,+1). Out of those, the first would be the best according to L1 (sum=2), but the second is the best L2 (sum of squares = 1.71), and the third is the best Linfinity (maximum difference is 1). Sep 24 revised What are the methods of dividing numbers to get weird values like $16\over 17$ without a calculator? added 1 character in body Sep 24 answered What are the methods of dividing numbers to get weird values like $16\over 17$ without a calculator? Jul 17 comment Do the matrices with maximum determinant always have integral values +1, but I would clarify the wording of we can always set that element to either 0 or 1 without decreasing the determinant. To me that sounds like we can set it to 0 or 1 will never decrease the determinant, when in reality usually only one of those values will not decrease the determinant. Jul 8 comment Why does one third belong to the Cantor set? @Brian Another way would be 7. Jun 15 revised How can we simplify the expression $P+\sqrt{ (P^2+\sqrt{ (P^4+\sqrt{ (P^8+…)}}}$?

Dec 16 comment Getting percentage difference between two numbers? x = 100*5000/80000 = 500000/80000 = 50/8 = 6.25 Dec 16 comment Getting percentage difference between two numbers? That is a raise of $5000 per $80000. Percent means per hundred, so to convert that to a percent, we just solve x/100 = 5000/80000 for x.
