Ua riro te GeoGebra ei faanahoraa roro uira no te haapii e no te haapii i te numera e te ihi mai te fare haapiiraa tuatoru e tae atu i te fare haapiiraa tuatoru. E nehenehe te mau vahi, te mau vector, te mau tuhaa, te mau reni, te mau polygon, te mau tuhaa conic, te mau au ore, te mau polynomial e te mau ohipa e hamanihia e hamanihia. E nehenehe te reira atoa e tauihia ma te puai i muri iho. E nehenehe te mau hu'ahu'a e tomo e e tauihia na roto i te kiore e te tape'araa, e aore râ, na roto i te afata tāuru. E nehenehe ta GeoGebra e faaohipa i te mau tauiraa no te mau numera, te mau vectors, e te mau tuhaa, e imi i te mau mea e noaa mai i te mau ohipa, e te vai ra te hoê faaueraa taatoa mai te Root aore ra te Extremum. E nehenehe te mau orometua haapii e te mau piahi e faaohipa i te GeoGebra no te rave i te mau mana'o e no te ite e nafea ia haapapu i te mau mana'o geometric.
What a cool trade-free software. Trade-free, because it doesn’t want anything from you like data, attention (ads) or currency. And cool, because of the many features it provides. I remember even my teacher in school showed us that program. However, on the website, google analytics is used, which, of course, collects data about the visitors. That’s why I give 4/5 blocks.
