WHICH SCIENTIFIC CALCULATOR?
While the fx-83GTX / fx-85GTX is adequate for GCSE, the advanced scientific fx-991EX confers specific advantages. In particular, it builds students confidence in solving
- linear equations
- simultaneous linear equations
- roots and vertices of quadratics
- quadratic inequalities
SHOULD I USE A GRAPHIC CALCULATOR?
Maths is a visual subject. A graphic calculator allows students to explore graphs. For example you could plot a graph, find the coordinates where two graphs cross or draw a data chart.
