Without further context, it is difficult to determine why the "10" is crossed out in the hundreds column. However, crossing out the "10" could indicate an error, correction, or a change in the numerical value in that position. It would be necessary to have more information or a specific example to provide a more accurate answer.
The 10 is crossed out in the hundreds column when counting because it represents a group of 1 hundred. Whenever you reach 10 groups of 1 hundred, also known as 1 thousand, you cross out the 10 in the hundreds column and move to the next place value. This helps keep track of the counting process and makes it easier to read and understand large numbers.
