you are saying you have to change the battery every few days, is this true or should i look for another financial calculator, as i use it for re ??

No need to change batteries every few days. The battery lasts for a few years.

Does this also work by solar. I have an older on that does. Just wondering?

No battery operated only on this model.

Caalculatrice financière

J'avais une ancienne calculatrice Texas Instrument. Celle ci la remplace aisément et est de très bonne qualité. Achetée il y a déjà longtemps elle me donne toute satisfaction.
