Guys believe me, i have used both fx-991es and fx-991es plus. But, fx-991es works faster than fx-991es plus. So, this is a great choice. You can solve matrix, table, vector, equation, integration and differentiation with it faster than fx-991es plus.

**Item is brand new. You will receive a user manual and a packet. I will open the seal to check that it works perfect. Thank you.
