Answers to Questions
How to make a formal calculation?
dCode brings you a formal/symbolic calculator which authorizes all calculations and answer an exact result (non-approximate) with the most simplification possible.
Example: Simplification of polynomials with variable: $$ x^2-(x-1)(x+2)+2x = x+2 $$
Example: Computation with unknowns: $$ a+1+a-2 = 2a-1 $$
dCode gives also an equation solver, and other calculus tools such as derivatives, primitives, etc.
