geogebra
Geogebra was fun easy to get started with.There are difficulty at some part .But it gives me option on how to figure out new ways with math and its easy to access the geogebra because at school we can access the computer and also at home, we could finish our work without having to worried that we could not finish at school. So geogebra makes our job less.
