• Open Genius Maker software and click "Permutation and Combination" button. It opens the Permutation and Combination window.
• Using "Select the condition" box, you can switch between Permutation and Combination.
• The middle box provides interface for entering input and reading output.

EXAMPLE - 1 ( Permutation )

• Let us compute 6P2
• Cilck "Permutation" button.

• Enter the value of n as "6"

• Enter the value of r as "2"

• Click "Solve" button.

• Now we can see that the software solves for 6P2 and displays the result of nPr as " 30 ".

EXAMPLE - 2 ( Permutation )

• Let us find the value of 'n' , where  nP5 =  240240
• Cilck "Permutation" button.

• Click "Clear data" button.

• Enter the value of r as "5"

• Enter the value of nPr as "240240"

• Click "Solve" button.

• We can see that the software solves for the unknown and displays the result of n as "14".

EXAMPLE - 3 ( Permutation )

• Let us find the value of 'r' , where  16Pr =  57657600
• Cilck "Permutation" button.

• Click "Clear data" button.

• Enter the value of n as "16"

• Enter the value of nPr as "57657600"

• Click "Solve" button.

• We can see that the software solves for the unknown and displays the result of ' r ' as "7".

EXAMPLE - 4 ( Combination )

• Let us compute 22C12
• Cilck "Combination" button.

• Click "Clear data" button.

• Enter the value of n as "22"

• Enter the value of r as "12"

• Click "Solve" button.

• Now we can see that the software solves for 22C12 and displays the result of nCr as "646646".

EXAMPLE - 5 ( Combination )

• Let us find the value of 'n' , where  nC24 =  62852101650
• Cilck "Combination" button.

• Click "Clear data" button.

• Enter the value of r as "24"

• Enter the value of nCr as "62852101650"

• Click "Solve" button.

• We can see that the software solves for the unknown and displays the result of n as "40".

EXAMPLE - 6 ( Combination )

• Let us find the value of 'r' , where  32Cr =  565722720
• Cilck "Combination" button.

• Click "Clear data" button.

• Enter the value of n as "32"

• Enter the value of nCr as "565722720"

• Click "Solve" button.

• We can see that the software solves for the unknown and displays the result of ' r ' as below.

" 15 and 17 "

• This implies that the current problem has 2 solutions. One is " r = 15 " and " r= 17 ". In other words it implies that  32C15 = 32C17 = 565722720

• Calculation Display: Whenever a problem is successfully solved, we can see the calculation of that problem in the "Calculation" box.
