It is easy to use ,it has a good introduction booklets. I highly recommend it

Barbie pink scientific calculator whose scientific functions are so easy to use that my Small Person uses it without issue. The screen is a good size and it feels like decent quality.

Got this out of nostalgic curiosity for the days before use of calculators in schools shunted programmability to top end professional devices. AFAI can make out it is similar to the old Casio fx-6300g kit.Pleasant for taking me on a trip down memory lane but these days, if you want a programmable device, then I think you're better off getting a top-of-the-line model from one of Casio, HP, Sharp or TI. (I use an HP50g, which beats the pants off this Catiga offering.)It's minor saving grace is that it's probably the cheapest programmable you can buy.

I used this calculator for my maths GCSE. The graph questions always get me confused. This answered the questions and drew the graphs and literally SAVED my education. Expensive? Yes but worth it? 100%

I got my calculator today and noticed the display was a bit faint, so I decided to change the brightness man I didn't know what I was getting myself into it's like a thick wall not really answering you very well that booklet. You can't change brightness on the machine, nor does it come with alternate formats for fractions such as math0 as well as the buttons are pretty slippery compared to Casio calculators

CATIGA calculator can make graphics, can solve equations in graphic mode, you can make programable formulas with 8 variables, can solve numeric integrals, Simpson method, the booklet which came with the calculator explains everything
