A powerful computer software for doing mathematics.
Presently I have introduced it in my school and teachers are glad. I offer free installation and it's light to use. I published a complete user guide recently. Any interested school can visit my site. I have close to 70 software published. Why so much hype about Geogebra? The university of Cambridge endorsed this among others. Run quickly and install.
