> But that doesn't work... if that is of any help, i came up with the same result after solving it exactly like you did, without reading your result first. that doesn't make it ricght, of course, but i've made another test and the odds are one in a million that we're both wrong:
var y:Number = Math.random(); var s:Number = Math.random(); var w:Number = Math.random(); var b:Number = Math.random(); var i:Number = Math.random(); var c:Number = ((y - s) / (w - b - s)) * i; trace( "test: " + ( Math.round( y * 1000000 ) == Math.round( ( ((c / i) * (w - b - s)) + s ) * 1000000 ) ) ); // traces "test: true" hth, mark On 3/19/06, Steven Sacks <[EMAIL PROTECTED]> wrote: > Hey everyone, > > My algebra seems to be failing me.
