Multiplying variables in Bash

Multiplying two variables is a simple operation in Bash. We can use the arithmetic operator * to multiply two numbers in Bash.

In Bash, multiplication is a step-by-step process. Follow the steps below to multiply two variables in Bash.

  • First, initialize two variables.
  • We then use the operator $(...)with *or an external program expression expr to multiply the variable.
  • Make sure to assign the above multiplication to a variable.
  • Echo the final variable.

Now let us implement variable multiplication according to the above steps.

Number1=555
Number2=666

Result=$((Number1 * Number2))

echo $Result

The above code will multiply two variables Number1 and Number2 using the $(...)multiplication *operator with and then echo the result. See the output:
