• Maths/numeracy lessons
• Whenever calculations are required.
• Generally, this calculator is useful in a high school setting, however, it is recommended that students have the opportunity to learn how to use the calculator before they reach high school so that they are comfortable and familiar with the layout of the buttons.
• Devices such as the BrailleNote Apex/Touch feature calculators for more common calculations, however the TI-84 provides the opportunity to complete the more complex calculations and graphing elements required in some high school mathematical courses.

Below is an outline of the Orion Ti-84 Calculator. This outline is designed to be printed in A3 size and then have braille added to it, so that a student can learn the layout of the keys. The calculator uses the same buttons to perform three different levels of functions (for example, the multiplication button is also the left square bracket ([) and the letter 'R'. By adding braille a student can use the outline as a mud map to independently learn the layout of the calculator.
