1By Lord HelmutSo deleted.#### Not a fan of subscriptions

3By Rambo8649Very cool app, seems to work so far with algebra. My only gripe so far is the subscription model...I can’t stand subscriptions, and this app doesn’t seem like one that would need it. I just want to pay one fee.#### Isss güd

4By RichKluIt’s a güd ol’ application#### It's great!

5By Mohammed Al_RawiThis app is wonderful, never saw app like this before. It has the ability to solve variable more the expected. Thanks a lot ❤️.#### Amazing app

5By ZmasterJamMath 42 helps so much with homework, like it literally shows an explanation for everything it is so good. My grades have improved because of it.#### Perfect

5By auriane.00Very helpful#### Used to be Free

1By SCAgamerThis app used to be entirely free. Now days, if you don’t pay a sub fee, the app looses all of its functionality acting as just any other calculator. Waste of space for someone who has no means of paying sub fees.#### Awesome App!!!

5By Tdoc 12Yes!!#### A surprise!

4By attackdriverVery effective tool and I was surprise overall at how well the app works and explains/ puts answers into context. Only used with algebra so far.
