Okay naman usable, nakakapag shift solve, kaya mag solve ng complex number. Wala naman issue wag lang siguro ihulog baka masira agad. Walang brand name, kapag inoff wala din lalabas na brand name like casio.

I’ve been using it for at least an hour and I must say it’s great! The buttons are working well too and it’s really perfect for shs students for bcal and other math subs. If you’re an upcoming shs student and in a budget then this is for you.

it’s working naman, and okay din naman siya nung dumating. Ang bilis rin ng delivery, kaka-order ko palang kahapon pero dumating na agad ngayon. A little suggestion for seller na i-buble wrap sana ang items para mas maging safe. ❤️❤️
