# Calculator

Our simple calculator allowing you to perform basic operations.

Input your operation (see the How to Use section below for help):

## How to Use

This calculator can perform basic operations of addition (+), subtraction (-), multiplication (*), division (/), power (^), root (\), and modulo (%). You can enter a basic operation like:
3.57+6.78
(Without spaces)

Use parenthesis to group:
(3+5)*4
(2*(3+5))^2

And use the less than sign (<) to retrieve the result of the last calculation performed:
(3+5)*<
This retrieves the result of the previous operation and multiplies it by 8. You can also use multiple <s to retrieve earlier operations:
(2+<<<)*3
This retrieves the result of the third previous operation (3+5)*4 and multiplies it by three after adding it to two.

When using the root operation (\: located between the Backspace and Enter keys), to take the square root, perform: 2\4 to get 2, or simply \4. The modulo operation takes the remainder of the first operand divided by the second (27%4=3, 8%2=0).
