This article will explain how to work out the number of double,trebles or accumulators when you place a bet.

Also it will explain how you can make more than one selection in a bet - it does not matter if horseracing or sports bets - and perm your selections.

If you you do want to perm your bets to increase your chances,you can have the same number in each race,or even have different numbers in any or all races - will refer to races in this article,but its just the same when betting on any sport.

In fact you can perm different race or sporting events with totally separate races within each unit - lets start by explaining how to work out the numbers involved - its quite easy.

#### How Many Doubles in Multiple Selections ?

Simple,just multiply backwards the number of selections(in doubles it is of course 2)and divide by the number of selections forward(again 2).

Its easier to demonstrate.

Lets do doubles in 3 selections

3 times 2 divided by 2(you are just counting backwards from 3 - because there are 3 selections - and forwards from 1.

3 Races = 3 times 2 divided by 2 = 3 doubles.

Lets do doubles in 4 selections.

Exactly the same.

4 times 3 divided by 2 = 6 doubles

Lets do number of double in 10 selections.

This looks as though it will be hard - not so,just the same and just as quick.

This time 10 times 9 divided by 2 = 45 doubles.

You will quickly realise that there is no need to work out full equation - look at it and bring the top fraction down for easier calculation - in the above example of 10 selections you will automatically divide the 2 into the 10 to bring down to 5 and then multiply that figure with the 9 (you can't divide the 2 into the 9 so that has to remain in equation - in doubles just halve the EVEN number).

I will explain how to perm later in article,but grasp basics first.

##### How Many Trebles in Multiple Selections ?

Exactly the same as calculating doubles,but this time you have to go further steps to work out the number of trebles.

Lets do number of trebles in 4 selections.

Exactly same principle as doubles,but this time you need to go 3 places.

So,again go backwards from 4(there are 4 selections this time) 3TIMES

And again go forward 3 times.

So,trebles in 4 is 4 times 3 times 2 divided by 1 times 2 times 3

In effect 24/6 or 4 - the number of trebles in 4 selections is 4

Again look at equation - there is no need to work out in full - bottom 2 cancels out top 2 and bottom 3 cancels out the top 3 - and that only leaves the 4 !

Lets do trebles in 8 selections.

Looks hard,but it is easy and quick - you will not need any tables or consulting websites to work out any bet once you have grasped this !

Trebles in 8 selections is 8 times 7 times 6 divided by 1 times 2 times 3

This time you don't want to work out in full - its hard work - so cancel down.

The bottom 2 goes into 8 and turns it in to 4,and the bottom 3 goes into the top 6 making that 2.

So,the new equation is now 4 times 7 times 2 = 56 trebles in 8 selections.

Lets do trebles in 12 selections

Just to demonstrate how large numbers can easily be calculated quickly this way.

So,12 times 11 times 10 divided by 1 times 2 times 3.

Knock that 12 down to 2 by dividing the 2 and 3.

This makes simple equation 2 times 11 times 10 = 220 trebles in 12 selections.

How Many 4 timers in Multiple Selections ?

Same as before - just go 4 places now.

Lets do 4 timers in 6 selections

So,6 times 5 times 4 times 3 divided by 1 times 2 times 3 times 4

Cancel down however you want - take out top 6 with 2 times 3 ,and cancel top 4 with bottom 4.

That leaves just 3 times 5 = 15 4 timers in 6 selections.

4 Timers in 10 selections

10 times 9 times 8 times 7 divided by 1 times 2 times 3 times 4

Makes 5 times 3 times 2 times 7 = 210 4 timers in 10 selections.

To work out higher accumulators than 4 - just go 5 places for five timers,6 for 6 timers and so on.

###### Perm your doubles in multiple bets.

Its is a good tactic to perm selections - particularly for forecast doubles and trebles bets - or whenever the odds are high and the races hard where you feel you need more than one selection to have chance of collecting.

You know now how to work out the number of doubles in any number of selections.

What you need to do now is multiply the number of doubles with the number of outcomes for each double.

2 Selections,or reverse forecasts in a perm.

Remember if you do forecast doubles you can either reverse your selections,or maybe use better option of 2 separate straight forecasts - it is exactly the same numer of bets.

So,if you have 2 selections in 2 races then there are 4 possible outcomes (2 times 2 = 4)

Just multiply the number of doubles by 4.

Maybe you have done 2 selections in 4 races.

You know the doubles in 4 selection is 6 - just multiple that by 4 = 24 bets

8 races is 28 doubles - multiply by 4 = 112 bets.

Perm your trebles in multiple bets.

Exactly the same as above,but now you must multiply the number of trebles by 8 as there are now 8 different possible outcomes (2 times 2 times 2 = 8)

You can perm 4 timers and above,but it gets a bit too expensive as you need to multiply 4 timers by 16.

Things to consider

Remember,you don't need to make selections in one race but you can put 2 selections together from different races - you now have 4 winning chances as opposed to just one winning chance if both selections for all doubles are from same race or sporting event.

Also there is no need to put 2 selections in every bet unit - just put one selection in one part and 2,or even 3 choices in another section - just multiply out each individual double and add through for total bet stake.
