Bash is the most commonly used shell (command line interface) under Linux, and bash itself is also a scripting language. Bash itself has no mathematical function, but it can be used with other tools under Linux shell.

For example, with bc, you can:

$ echo 5+30 BC

35

$ echo 5*30 | bc

150

$ Echo 5 3 BC

125

It means 5+30 = 35, 5x30 = 150, and the cubic of 5 is equal to 125.
