It is easier to simply add two one-digit numbers than to mess about with estimation!

999,999 is 6 digits Adding 1 makes it 1,000,000 = a 7 digit number.

Add the last digit (units digit) to twice the previous digit (tens digit). If this sum is divisible by 4, so is the original number.

Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.
You line up the last numbers and then add it!

Well, aren't you a little math whiz! Technically, if you add two two-digit numbers together, the sum will always be a two or three-digit number, not a four-digit number. So, nope, you can't get a four-digit number by adding two two-digit numbers. Keep crunching those numbers, smarty pants!

To divide a single digit number by a double digit number,you first have to understand its obviously isn't easy. The following should help: *Put a zero on the area of the quotient and add a decimal point next to it. * After doing this,divide as if both numbers were two digit numbers and proceed You should get the answer.

Add the last digit (units digit) to twice the previous digit (tens digit). If this sum is divisible by 4, so is the original 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.
