Assuming you meant the largest 3 digit number without repetition:
Largest 4 digit without repetition = 9876
Largest 3 digit = 987
⇒ difference = 9876 - 987 = 8889
0
With repetition, there are 86 ( = 262144) such numbers. Without repetition, there are still 8!/2! = 20160.
you wil have to figure it out, is it your homework?
The difference between a hypothesis and a conjecture is that a hypothesis is something investigated or accepted as highly probable in the light established facts and a conjecture is the formation or expression of an opinion or theory without sufficient evidence for proof.
-- write the difference between the integers without regard to their signs -- give the difference the same sign as the larger of the two integers
Largest 4 digit number with repetition is 9999 Largest 3 digit number without repetition is 987 Difference is 9999 - 987 = 9012.

9876-987=8889

9876-102=9774The largest 4 digit number, without repetition, is 9876.The smallest 3 digit number is 102.Their difference is 9774.
9876-102 9704
9999 - 102 = 9897
1
The largest 4 digit number with repetition is 9999. The smallest 3 digit number without repetition is 102 9999 - 102 = 9897
9999-1023 = 8976
