What is a 3 digit whole number when doubled remains a 3 digit number When you add 2 to the doubled number it becomes a 4 digit number?

Any number when doubled becomes even. Thus the key part of the question is identifying a 3 digit even number that you can add 2 to to become a 4 digit number. The answer is 998. Thus to find the original number we need to do 998/2. This calculates to 499.


If you add a two digit number to a two digit number do you get a four digit number?

No. When adding the smallest 2 digit number (= 10) to the smallest 2 digit number (again, 10) the result is a 2 digit number (10 + 10 = 20). When adding the largest 2 digit number (= 99) to the largest 2 digit number (again, 99) the result is a 3 digit number (99 + 99 = 198). As you can see, you'll either get a 2 or 3 digit number, but never a 4 digit number.

What is a digit sum of a number?

To find the digit sum of a number you plus the first 2 numbers together, example:the number 18, 18 is made up of 2 digits 1 and 8.If you add the 2 digits together you get a total of 9.So that is the digit sum of 18.But if you use a higher number like 66 then the method has a small change.First if you add the two digits together it becomes 12.But 12 isn't a single digit sum.So again the 2 digits have to be added together to make a single digit sum.1+2=3 so 3 is the single digit sum for the number 66.
