# Calculator in Python Tkinter



   



#### Some explanations for each button and the function which represents are the following : 

- **1st Row**



   



  

1. **abs** : The absolute value of a number (e.g. abs(-5) = 5).

2. **mod** : From *modulo*. it's the operation to find the remainder of the division of one number by another.  

             In python we use the symbol %  (e.g. 5mod2 = 5%2 = 1).  

3. **div** : Floor division returns the result of the division rounded down to the nearest integer.  

           In python we use the symbol //  (e.g. 8div3 = 8//3 = 2).

4. **x!**  : The factorial of the number x (e.g. 4! = 24).

5. **e**   : The Euler's number. A mathematical constant approximately equal to 2.71828.  


- **2nd Row**



   



1. **sin** : Sine of an angle θ in degrees (e.g. sin(90)=1).

2. **cos** : Cosine of an angle θ in degrees (e.g. cos(180)=-1).

3. **tan** : Tangent of an angle θ in degrees (e.g. tan(45)=1).

4. **cot** : Cotangent of an angle θ in degrees (e.g. cot(45) = 1/tan(45) = 1).

5. **π** : Archimedes' constant defined as the ratio of a circle's circumference to its diameter.  

       It is approximately equal to 3.14159.

- **3rd Row**



   



1. **x2** : x raised to the power of 2 (e.g. 42 = 16).

2. **x3** : x raised to the power of 3 (e.g. 53 = 125).

3. **xn** : x raised to any power (e.g. 24 = 16 ).

4. **x-1** : x raised to the power of (-1). The inverse of number x (e.g. 2-1 = 0.5).

5. **10x** : Powers of 10 (e.g. 103 = 1000).

- **4th Row**



   



1. **2√** : Square root of a number (e.g. 2√144 = 12).

2. **3√** : Cube root of a number (e.g. 3√8 = 2).

3. **√**  : Any root of a number (e.g. 4√16 = 2).

4. **log10** : The logarithm of a number with base 10 (e.g. log101000 = 3).

5. **ln** : The logarithm of a number with base e (e.g. logee = ln e = 1).

- **5th Row**



   



1. **(** : Left parenthesis.

2. **)** : Right parenthesis.

3. **±** : Change the sign of a number.

4. **%** : Find the percentage of a number (e.g. 5% = 0.05).

5. **ex** : Expotential function (e.g. e2=approx 7.389 ).

- **6th,7th,8th,9th Row**



   



In these rows are :  

-> The basic number buttons (0 to 9).  

-> The basic math symbols (operators) (+, -, *, /).  

-> The equal sign (=) and point (.).  

-> Button **DEL** to delete one or more from the end of the entry.  

-> Button **AC** to delete the whole entry.  

-> **EXP** : Multiply any number with powers of 10 (e.g. 2 * 10 ** 3 = 2000).
