# Dice and Calculators

## Winning Dice

Rolling a dice is easy to understand and the true odds of rolling any number are very easy calculate - it's got 6 sides and they all have the same chance of being on top, so that's like 1 to 5 (once for your number and five times for the other numbers). It's quite an eye-opener to see how easy it is to lose a fortune when your number waits a long time before showing.

Winning Dice illustrates what happens when a gambler hopes to be happy.

The illustration uses a single dice with 6 sides and no way of knowing which number is likely to win.

You can choose:

• how much you'd like to make in a year
• how many bets you would place each week
• how many weeks each year to be betting
• at what odds you would bet

There are two scenarios:

• level bets, where the same bet is placed every time and you know that if the odds are fair you won't lose in the end
• variable bets, where the bets are calculated to recover earlier losses so that you end up without loss if you bet at fair odds

Fair odds on a dice would be 5/1. No bookmaker would offer those odds as bookies are not gamblers and need to make a profit, and the logic is very simple. However, the illustration shows what can happen at 4/1, 5/1 and 6/1.

I hope you enjoy seeing what could happen if you bet at poor value or bet at good value and that, even betting at good value, the variable betting method is still impossible.

## Calculators that can be edited

Freeform Calculator is exactly that.
It's free; it's freeform - insofar that it doesn't have a particular form; it's like a tape calculator that performs most of the normal types of calculation that most people require. It's designed for phones and tablets and also works in any browser on a PC or Mac.

Freeform Calculator works using the same conventions as Excel: multiplication and division occur first, addition and subtraction second. Using brackets ensures certain things are grouped for calculation. It doesn't do scientific calculations or trigonometry or raising numbers to powers, but it does do simple things a whole lot easier and with less fuss than Excel.

Pass The Bill is another calculator.
This uses the same engine as Freeform Calculator but is specifically designed for phones and tablets to split bills and share them fairly when you're eating with with friends.

Using Pass The Bill on a phone or tablet in a restaurant will remove the stress that often happens when a bill is presented and friends want to pay just for their fair share of the bill. You can calculate what each person should pay based on their individual items and on the items they shared with others. Then you can add tips based on those amounts.

It was a difficult decision whether to call this app "pass the bill" or "parse the bill". Search engines could mistake pass for parse or vice versa, but the word parse has a meaning that properly describes the process as being a separation of the parts into distinct sections - text and numbers.
