In order to get the greatest number we want to try and get the biggest possible numbers in the hundred thousands, ten thousands and thousand places. There is no rule against the hundred thousands digit being 9 so it must be 9. The ten thousand digit needs to be twice the tens so it must be 8 while the tens is 4. The thousands digit is divided by the units, and the number is even. So thousands must be 6 and the units must be 2. Thus the hundreds must be 7. The number is 986,742

I am a four digit number. My tens digit is 2 more than my ones digit. My hundreds and thousands digit are both 1 less than my ones digit. What number can i be?

The rule of rounding numbers is that if a number is 4 or less it becomes 0, and if a number is 5 or more it becomes a 0 and the number immediately to the left of it increases by 1.If you want to round to the nearest ten thousand, look at the number in the thousands position; if that number is 4 or less the ten thousand digit will remain the same and the thousands digit will drop to 0, but if that digit is 5 or more the ten thousand digit will increase by one and the thousands digit will become 0.For example, take the number 123,456 (or one hundred and twenty-three thousand, four hundred and fifty-six)To round that to the nearest ten thousand look at the ten thousand position digit (which is the 2) and take the digit immediately to the right (which is the 3 in the thousands position). Because 3 is always rounded down the 3 becomes a 0, and so we now have 120,000, or one hundred and twenty thousand.If instead we take the number 126,789 (or one hundred and twenty-six thousand, seven hundred and eighty-nine), the number in the ten thousand position is still the 2 - which is the number we are rounding to - and the digit immediately to the right is a 6 this time.Because 6 is more than 5 (see above, way back up there ^^^ at the start) the 6 becomes a 0 and the number immediately to the left in the ten thousand position increases by 1 so the rounded number is now 130,000 or one hundred and thirty thousand.
While it is a rather large number, on the biggest number scale the Graham's number is the largest by far. See the related link for more information.
write the number that is 500 more than the biggest number that can be formed by all the odd 1 digit number
97531 + 500 = 98031.
