Calculator ∞ App Reviews

Im satisfied.

This App calculated: 1)Sigma{log(x);x=1~100000)} as 456573.4509 in a split of a second! ; 2) 4*Sigma{(-1)^x/(2x+1);x=0~100000} as 3.1416••• in approx.3seconds! >> Is there any other challenger to this speed?

Easily to be used

Just started using this calculator. It is easy to follow and easy to use. Screens are well organized so that even first time user can easily adopt. Additionally I have asked few questions to help desk of this software. Response was very accurate and extremely quick, surprised!! Better try this

What i needed it for

This is the best calculator Ive ever used. The first time I opened this app, it was magnificent. I will now be conquering all of my math and algebra classes. I rate 5/5 for this godsend.

This is an excellent calculator with many features including symbolic algebra. Well worth the cost. The instructions could be improved.
