+# Mathematical Expression Calculator
+
+This is a simple Python console program that calculates mathematical expressions with two operands. It accepts a string as input, which contains a mathematical expression with two numbers (integers or floats) and one of the four operators (+, -, \*, /). The program then calculates the result and displays it on the screen.
+
+### *Features*
+___
+- Supports four basic arithmetic operations (+, -, \* , /)
+- Handles both integers and floats
+- Checks for division by zero errors
+- Provides error handling for invalid input
+### *Requirements*
+___
+- Python 3.6 or later
+### *To install*
+___
+- Clone the repository or download the zip file
+- Make sure Python 3 is installed on your machine
+#### *Developed by*
+___
+- Gorenkova Anastasiia (create main function)  
+- Kokinos Elena (create addition function)
+- Parfenova Polina (create multiple function)
+- Shchukina Elza (create difference function)
+- Zhidkin Roman (create division function)
