+# Calculator project
+This small project is a simple calculator of ours. The goal of this script is to upgrade our teamwork skills and get acquainted with git and Git Hub
+
+## How to use the software
+1. Run the *calculator.py* script with `python3 calculator.py` from your Terminal.
+2. The script will need you to enter a simple mathematical expression. Like "5 + 10" or "6 / 3". 
+3. Our project supports 4 basic operation: addition (+), substitution (-), multiplication (\*), division (/). Make sure your expression has only one those operators.
+4. Enjoy your answer :)
+
+## List of developers
+- Team Lead and main(): Alina Tagirova
+- Addition: Maria Bicktasheva
+- Substraction: Konstantin Yamschikov
+- Multiplication: Arseniy Melnik
+- Division: Sergey Losev
