Transcribed Image Text:For Questions 24-26. According to the creator of GeoGebra, they focus now on the development
of the free software on mobile devices. He argued that with the current and future capabilities of
the platform, it might replace calculators in the future considering that almost all students now
have smartphones. In line with this, a researcher asked 200 randomly selected college students
whether they prefer to use mobile phones over calculators. The result shows that 88 students
prefer mobile phones.
