Step 2: ,[object Object],13 2 12 = 12 + 2 12 = 13 = 12 12 12 2 12 + 1 + + 2 12 + = 12 14 12 13 2 12

Step 2 continued… ,[object Object],13 - 6 9 12 = = 6 9 12 12 14 12 2 12

Step 3: ,[object Object],6 9 12 12 14 12 - 5 12

Step 4: ,[object Object],6 9 12 12 14 12 - 5 12 6

Step 5: ,[object Object],[object Object],5 12 6

Step 2: ,[object Object],8 15 40 = 7 + 15 40 = 8 = 7 40 40 15 40 + 1 + + 15 40 + = 7 55 40 8 15 40

Step 2: ,[object Object],[object Object],6 5 35 = 5 + 5 35 = 6 = 5 35 35 5 35 + 1 + + 5 35 + = 5 40 35 6 5 35
