What is a double digit number?
It is a number with two digits in it. So it goes into the "tens" place of the numbers. Basically any whole number from 10 to 99. See how any number between those numbers only has 2 numbers, or digits that make up the number? 9 would only be a single-digit number, and 100 would be a triple-digit number.
How do you calculate how many numbers you can make from a 6 digit number without repeating digits in any number?
Besides no repeats, we also assume that the first digit can't be zero.The first digit can be any digit except zero ... 9 choices. For each of those . . .The second can be any one of 9 digits ... zero, and the 8 that were not the first one. For each of those . . .The third can be any one of the 8 remaining digits. For each of those . . .The fourth can be any one of the 7 remaining digits. For each of those . . .The fifth can be any one of the 6 remaining digits. For each of those . . .the Sixth can be any one of the 5 remaining digits.The total number of possibilities is: (9 x 9 x 8 x 7 x 6 x 5) = 136,080 .If there were no restrictions, then 6 digits could make 1,000,000 different numbers.The restrictions have eliminated 86.4 percent of them.

For each of those . . .The ninth can be any one of the nine digits not the same as the eighth.The total number of possibilities is: (10 x 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9) = 430,467,210 .If matching adjacent digits were allowed there would be 1,000,000,000 possibilities.So the restriction has eliminated 56.95% of them.
