The significant digits in a number can be arbitrarily small or large in number, according to the method of creating them.Numbers that can have an infinite number of possible significant digits are called transcendental numbers.
-- "The sum of a two-digit number" is unclear. I took it to mean"The sum of the digits of a two-digit number."-- "... the product ?" is unclear. Are you looking for the product of the two digits,or the product of the forward and backward numbers ?-- It's not possible to write a number whose two digits sum to 12 and whosereverse exceeds it by 25. The tens digit would have to be 4.611... and the unitsdigit would have to be 7.388... .Then(4.611...) + (7.388...) = 12(46.111...) + (7.388...) = 53.5(73.888...) + (4.611...) = 78.5Difference = 25So, the number can't be written, but ...The product of its two digits is 34.071 (rounded)The product of the forward and reverse numbers is 4,199.75 (rounded)
Integers of 6 digits are normally greater than integers of 5 digits
Using the digits, we can make 81 x 62 equals 5022, which is the largest possible product.
Using the digits, we can make 81 x 62 equals 5022, which is the largest possible product. To make the smallest possible product, do 268 x 1 = 268.
93 x 862 = 80,166

0.12 Or 102 if you do not want to include non integers.
Assuming that the given digits are significant digits, then 0.05
52 is a number whose digits have a product of 10.

The greatest possible number is 888... (repeating).
-- The greatest number you can write with those digits is 8,633 . -- If you're going to multiply them, then the order in which you put them makes no difference. The results of every multiplication will all be the same, regardless of their sequence ... just as the results would be if you add them.
