How many digit 4 in numbers from 1 to 623?
To determine how many times the digit 4 appears in numbers from 1 to 623, we can consider the units, tens, and hundreds place separately. In the units place, the digit 4 appears once in numbers ending in 4 (4, 14, 24, ..., 614). This happens 62 times. In the tens place, the digit 4 appears 10 times in every hundred numbers (40-49, 140-149, ..., 540-549), so it appears 6 times within the range from 1 to 623. In the hundreds place, the digit 4 appears once in every hundred numbers (400-499), occurring 1 time. Therefore, the digit 4 appears a total of 62 + 6 + 1 = 69 times in numbers from 1 to 623.

When writing numbers from 1 to 10000 how many times is the digit 9 written?
To determine how many times the digit 9 is written when writing numbers from 1 to 10000, we can consider the pattern of its occurrence in each place value. In the units place, the digit 9 appears 1000 times (from 9 to 9999). In the tens place, the digit 9 appears 1000 times (from 90 to 99, 190 to 199, and so on). In the hundreds place, the digit 9 appears 1000 times (from 900 to 999, 1900 to 1999, and so on). Therefore, the digit 9 is written 3000 times in total when writing numbers from 1 to 10000.
