Question

numeral system or system of numeration is the writing system for

expressing numbers. Let’s play with numbers/ digits and record our

observations.

Write down counting numbers from 1 to 20 in an order. You will observe that you

have written 31 digits in all as numbers from 10 to 20 contain 2 digits numbers

also.

• Can you find the number of digits for counting numbers from 1 to 1000.

• Further, if 1000 digits were written in total how many complete numbers

(1- digit, 2- digit, 3- digit etc) would be written down?​

Answer 1

a)2893 is ur answer.

Step-by-step explanation:

a) 1–9 has 9 digits; 10–99 has 90*2 = 180 digits; 100–999 has 900*3 = 2700 digits; and 1000 has 4 digits.

So the total is 9 + 180 + 2700 + 4 = 2,893 digits

(If you want to add 0 for completeness, the answer is 2,894.)
