ways to write the code. However, the order of the rooms is arbitrary, so there are really only 7!/(4!×3!) unique arrangements. In general, you can choose r items in any order from n repeatable choices in (n+r–1)!/[(n–1)!×r!] ways. References Math Is Fun: Combinations an...
The "pattern" ruleis used to impose some kind of pattern to each entry. Example:pattern c,*means that the letter c must be first (anything else can follow) Put the rule on its own line: Example: the "has" rule a,b,c,d,e,f,g ...
There are other math tutoring programs and then there is Algebrator. No other software even comes close! Christopher Montomery, OH I am a parent of an 8th grader:The software itself works amazingly well - just enter an algebraic equation and it will show you step by step how to solve and...
In English we use the word "combination" loosely, without thinking if the order of things is important. In other words:"My fruit salad is a combination of apples, grapes and bananas" We don't care what order the fruits are in, they could also be "bananas, grapes and apples" or "...
