+# Solution
+
+## Calci
+
+Calci is a calculator that is built using Tkinter that is the de facto way in Python to create Graphical User interfaces. Calci can perform basic mathematical operations such as - Addition, Substraction, Multiplication and Division, in addition to this it is also capable of performing sine, cosine and logarithmic operations. The feature that makes Calci differnt from others is that it can perform calculations by taking input through user's voices.
