## The description of Electrical engineering calculator

"Electrical engineering calculator PRO " is especially designed for graduates of electrical engineering and professionals for helping and proudly easy their engineering tasks and projects with full feature. As our developing team, we take cognizance of using scientific calculator and using formulas. That is why we are quite against to offer our application to electrical engineering students since the application may produce a little laziness!

Both free and PRO versions of the application contains NO ADDS!
