Question 1125896
Comparing {{{645}}} and {{{738}}} is different from comparing {{{645}}} from {{{649}}} in a few ways. 

So going in order of the three digits we can see that the {{{645}}} and {{{738}}} begin with {{{different}}} number, one has {{{6}}} one has a {{{7}}}. 

In the second set,{{{645}}} and {{{649}}}, of numbers {{{both}}} begin with a {{{6}}}.

The {{{second}}}{{{ digits}}} of the {{{first}}}{{{ number}}} set also {{{differ}}}. One is a {{{3}}} the other contains a {{{4}}}. 

In the {{{second}}}{{{ set}}} of numbers the {{{second}}}{{{ digit}}} is the {{{same}}}, both have a {{{4}}}.

The {{{third}}}{{{ digit}}} of the {{{first}}}{{{ set}}} are also {{{different}}}, on being a {{{5}}} the other an {{{8}}}. 

In the {{{second}}}{{{ set}}} of numbers one of the {{{third}}}{{{ digit}}} is a {{{5}}} the other is a {{{9}}}.

Comparing the first two numbers of the second two numbers is different because the {{{difference}}} between the first two numbers is much larger.

{{{738 - 645 = 93}}}
 {{{649 - 645 = 4}}}

Lastly, we can say same for their sums and products too. They will {{{differ}}} too.
