If you mean, "What is the largest number of digits possible in the product of two 2-digit numbers" then 99 * 99 = 9801, or 4 digits. Anything down to 59 * 17 = 1003 will have 4 digits.

67/72 of them.
It means it is odd (ends in 1, 3, 5, 7, or 9), when you multiple the digits together you get 24 for an answer, and when you subtract the digits from each other you get 5. Hope this helps.
from 3 digits (10x10) to 4 digits (99X99)

52 is a number whose digits have a product of 10.
No, while the first three digits of the product barcode may sometimesindicate where the product was manufactured, it will not alwaysdo so. For example, a barcode that has 690 as the first three digits indicates that the barcode was assigned by the Chinese EAN numbering authority. However, it does not necessarily mean that the product was actually manufactured in China.

You had me until "product." The product of 4 digits can't be prime.
When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits. 310 × 20 = 6200 6200 already has two significant digits.

400 x 4 = 1600 Therefore, four digits.

-- "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)
