Arithmetic operations
Let’s start with the arithmetic operations since they are relatively simplest. Programming languages use regular symbols to denote them:

There are two more operations that are often used in programming. These are exponentiation and division with remainder.
Let’s suppose that we want to raise the number a to the power of b. We can write it as ab. Here, a is the base and b is the exponent. If we want to raise two to the power of seven, we write 27. The same operation in Bash looks like this:
