# Toptal First Project

## Statement 

Write a simple scientific calculator app with the following features:

* the calculator supports addition, subtraction, multiplication, division, log on floating point numbers

* the calculator can solve simple linear equations with a single variable (namely, x), for simplicity, only addition, subtraction and multiplication operations are allowed

* the calculator supports parentheses in both modes

* the calculator should have a language parser

* do not use any library that can accomplish any of the listed requirements

* the calculator should handle all error cases properly (by carefully indicating the errors to the user)

## Examples

input: (3+(4-1))*5

output: 30

input: 2 * x + 0.5 = 1

output: x = 0.25

input: 2x + 1 = 2(1-x)

output: x = 0.25
