This tutorial demonstrates how to multiply two variables in Bash.
Multiply Variables in Bash
Multiplying two variables is an easy operation in Bash. We can use the arithmetic operator *
to multiply two numbers in Bash.
Multiplying is a stepbystep process in Bash. Follow the steps below to multiply two variables in Bash.

. 
Make sure to assign the above multiplication to a variable.

Echo
the final variable.
Now let’s implement the variable multiplication based on the above steps.
Number1=555
Number2=666
Result=$((Number1 * Number2))
echo $Result
The code above will multiply the two variables, Number1
and Number2
, using the *
multiplication operator with $(...)
and then echo
the result. See the output:
