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.
Multiplying a 2-digit number by a 1-digit number involves multiplying the digits in the ones and tens place and then adding the products. Similarly, multiplying a 3-digit number by a 1-digit number follows the same principle, where you multiply the digits in the ones, tens, and hundreds place and then add the products. The main difference is that in the latter case, you are dealing with three sets of digits to multiply and add, whereas in the former, you only have two sets of digits.

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