The sum of any two-digit number and the number formed by reversing the digits is always divisible by what?
The sum of any two-digit number and the number formed by reversing the digits is always divisible by 11. This is because when you add a two-digit number to its reverse, the result will always be a multiple of 11. This is because the difference between the original number and its reverse is always a multiple of 9, and when you add two multiples of 9, the sum will always be a multiple of 11.
The sum of the digits in a two digit number is 10 if the digits are reversed the new number will be 54 more than the orginal number what is the orginal number?
Possibility of two digit no whose sum is 10 19,28,37,46,55,64,73,82,91 Add 54 to each no mentioned above result is 73,82,91,100,109,118,127,136,145 See after first comma 28 and 82 If you reverse 28 . 82 will come which is 54 more than 28. So 28 is that original number
How can you tell that 189 is divisible by 3 without doing the division?
Add up the digits in a number, and if that sum is a multiple of 3, then the original number is also a multiple of 3. So 1 + 8 + 9 = 18, which if you're still not sure then 1+8=9, which is a multiple of 3. You can repetitively sum the digits until you have a result of a single digit number. If the single digit result is 3,6 or 9, then the original number is a multiple of 3. Also, if the single digit number is 9, then the number is also a multiple of 9. However, if the result is 6, then it is not necessarily a multiple of six.
All the other digits are the result of subtracting any number from itself?
