Notice that the number 514,482,441 can be written as:
500,000,000+10,000,000+4,000,000+400,000+80,000+2,000+400+40+1
starting from the left:
the value of the first 4 is 4,000,000
the value of the second 4 is 400,000
thus the first 4 is 10 times the second 4
the value of the third 4 is 400
the value of the fourth 4 is 40
thus the third 4 is 10 times the fourth 4
The similarity is that both pairs of fours differ by a factor of 10
the difference is that the first pair of fours are larger than the second pair of fours, as described above.
