These are not equations, but assignments. In the first example, the value is never assigned to cnt1 (only to variable cnt), whereas in the 2nd example, it is..
do you find the following code (which also works for the case where n is 1) easier to understand:
Code:
#!/bin/bash
read -p "Enter number: " n
fact=1
i=1
while [ $i -lt $n ]
do fact=$((fact * (i += 1)))
done
echo "$n! is $fact"
I assume that you're using bash because read -p isn't in the standards and is not accepted by ksh (which would do this with read n?'Enter number: ').
Note, however, that if you want to compute factorials larger than 25! on a machine with 64-bit long ints, you'll need to use something with arbitrary precision arithmetic (such as bc or dc) instead of relying on shell arithmetic.
