Solving problem is an essential skill, involves more steps where sometimes it brings more confusion. I am suffering to solve calculative problems for long time. I have checked in Free Online Calculators @ https://www.calculators.live/index.php
In this, we can search for the calculator which we want to know and basic calculators are also given for reference. Currently, there are two basic calculators namely Algebra and Analytical are available with an example. What I want to know is: Is there any other online calculator explains the calculation with theorem?
