Question 12.
If I write the numbers 1 through 43, how many digits do I write?
_________________
Answer:
Numbers 1 through 9 are single-digit numbers. You will be writing the digits 1, 2, 3, 4, 5, 6, 7, 8, and 9, which give 9 numbers.
Numbers 10 through 43 are double-digit numbers.
10-19 give ten numbers. 20-29 give ten numbers. 30-39 give ten numbers. 40-43 give four numbers. So, there is the total of 34 numbers.
However, we have to find the number of digits.
Numbers 1 through 9 contain single digits. Therefore, a number of numbers times the number of digits in that category gives a total number of digits.
9 x 1 = 9 digits
34 x 2 = 68 digits
68 + 9 = 77 digits.
These are the number of digits written.
