When a person writes all 4-digit numbers, they range from 1000 to 9999, totaling 9000 numbers. The digit '2' can appear in each of the four positions (thousands, hundreds, tens, and units). In each position, '2' will appear 900 times (e.g., for the thousands place, numbers from 2000 to 2999), leading to a total of 3600 occurrences of the digit '2' across all four positions.
It is actually very simple, just take 10 to the square root of four. 10^4
