Is there any software or programming lang for getting maths answers step by step?
When I type the question it should give a brief answer,
for example
when I type (2+2)*2
it should show me
(2+2)*2
=(4)*2
=8
and it should not be like this
(2+2)*2=8
(it shouldn't be like a calculator that shows only the final answer).
For simple queries, Symbolab seems like a decent tool. This might be sufficient for your needs. Cymath seems to be a similar tool.
Wolfram Alpha has a paid "Pro" subscription service which can answer some queries step by step as well.
