Cual es la razon para invertir 35 dolares en tu fx-991es, si la calculadora fx-991ex vale apenas 20 dolares y tiene 135 funciones mas ?

Me gustó más su diseño, la utilizo como calculadora de bolsillo no programable únicamente , (utilizo una programable para ingeniería). el precio estaba en oferta cuando la compré, me costó casi lo mismo y me gustó más.

Easy to use.

My daughter had the exact same one for 3 years until it gave up on her. I bought this exact same one for her on her request. She loves the set up on it and how easy it is for her to use. Is valid to say he is autistic and this is must for her.
