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.

There are 90 different answers. If A is any 2-digit number (from 10 to 99), then B = 473 + A is a 3-digit number and B - A = 473
A three digit number is a number that has 3 digits. Example 382 3 is the hundred digit. 8 is the tens digit. 2 is the ones digit.

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.
You line up the last numbers and then add it!

A smaller 3 digit number or a 2 digit number (99).
Example: 222*12 222 3 digit * 13 2 digit ------- 666 Multiply 3 to all three twos +222 Multiply 1 to all three twos (skip spot) -------- 2886 Answer Add up
If you add together all the factors of the number six, you will get an answer of 12:1+2+3+6=12
next number to this series is 554325. its look like this 15--add 1 to first digit and we get 2 and repeat two times and leave other digit.225 225-- its first digit is 2 and add 1 to it get 3 and write two time and write remaining digit as 3325. 3325-- its first digit is 3 and add 1 to it get 4 and write two time and write remaining digit as 44325. 44325-- its first digit is 4 and add 1 to it get 3 and write two time and write remaining digit as 554325.

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.
Yes, unless the 3 digit number is negative, or a decimal.
1002 is the smallest 4 digit number divisible by 3 and 2.
