Question

How many numbers are there from $1300$to $15300$?

Answer 1

Understand the basic principle of counting

To find the numbers between $0$ to $9$

$0,1,2,3,4,5,6,7,8,9$ .There are $10$ numbers

We get to the number $10$ by $9-0+1$

We add $1$ because we exclude one of the two numbers twice

Hence, the numbers between two numbers $a$ and $b$$=b-a+1(b>a)$

Hence, the numbers between $1300$ and $15300$ $=15300-1300+1$

$=14001$

Hence there are $14001$numbers between $1300$ to $15300$
