easy to use while retaining all the functionality of the calculators they replace. It’s

  • easier to access operations

  • easier to read the 4 times higher resolution display
There is also new functionality to help with calculating ratios.
The GTX range has a natural maths display and covers all the mathematical requirements for first
examinations. Check out the full list of functions below.
