After primary (pilot) investigation of how well 8 computer algebra systems handle equations from school textbooks, it is possible to conclude that the systems are mostly reliable and give reasonable answers. Some remarks regarding a somewhat unexpected answer obtained can be easily explained by built-in standards and notions, which can differ from school assumptions. In other cases the differences from school could be corrected by certain commands.application/pdfcomputer algebra systemsschool algebraequationsfolyóiratcikkOpen AccessEno Tonisson and Nadezhda Velikanovahttps://doi.org/10.5485/TMCS.2008.0177Teaching Mathematics and Computer Science16Teach.
