Re: 10 second questions
Hi bobbym,
The solutions 2823 and 2824 are correct. Stupendous!
#2825. The difference between a two-digit number and the number obtained by interchanging the two digits is 63. What is the smaller of the two numbers?
#2826. If the number obtained on interchanging the digits of a two-digit number is 18 more than the original number, and the sum of the digits is 8, then what is the original number?

Re: 10 second questions
Hi;
I see what I did wrong for #2825. I used the larger number rather than the smaller one.

[A vinculum is a horizontal line placed over a mathematical expression, used to indicate that it is to be considered grouped together. Vinculum is Latin for "bond", "fetter", "chain", or "tie", which is roughly suggestive of some of the uses of the symbol. The vinculum was developed in the 12th century by the Moroccan mathematician Abu Bakr al-Hassar.]
