In the decimal place value system, each digit is ten times bigger than the digit on its right
No.
To find the product of a 2-digit number and a 4-digit number that is approximately 500,000, we need to consider the magnitude of the numbers involved. Since a 2-digit number ranges from 10 to 99 and a 4-digit number ranges from 1000 to 9999, their product will be in the range of 10,000 to 99,000,000. To get a product around 500,000, we can estimate that the 2-digit number is around 50 and the 4-digit number is around 10,000. Therefore, the product of a 50 and 10,000 is 500,000.
Yes, unless the 3 digit number is negative, or a decimal.
On a number line, the digits from 10 to 99 are all two digit numbers. How many numeber are that? There is a short cut. You can subtract 10 from 99 and that gives you the number of numbers between 10 and 99 including 10, but you need to add one more to include 99 as well. So, 10 from 99 is 89 adding 1 is 90 ,which is the amount of numbers total that are two digit. The probability of guessing a two digit number is 1/90 =D
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.

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.

No. Compare equivalent digits one by one, from left to right, until you find a digit where there is a difference. In this case, the number with the bigger digit in that position is also the bigger number.
999,999 is 6 digits Adding 1 makes it 1,000,000 = a 7 digit number.
The math works like this Lets call the original two digit number x, then adding a "3" to the right of x would translate into x*10+3 hence we have x = (10x +3) -372 x + 372 = 10x+3 372= 10x+3-x 372-3=10x-x 396 = 9x 396/9=x x=41 and if we test it, 41 with the added 3 would be 413 and 413 - 372 = 41 is true The original two digit number was 41

the greatest is bigger than the smallest
A) If a number has two digits, then the sum of its digits is less than the value of the original two-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.
