Recall that variables are single-letter representations of unknown quantities.
The equation editor allows for all English, Greek, Script, and Fraktur letters to be entered as variables. For example, you can use the Greek letter Theta (dots 46, 1456) to identify an angle measure, or use a Fraktur R to identify "all real numbers".
Type the following expressions into the equation editor below and verify that the equation editor produces the proper Nemeth braille output in each case. Also verify that a sighted friend can read each expression you have typed as it is displayed on the screen. Feel free to try your own examples.
- x = 4
- x + 4 = 5
- 3q * 4 = z
- y = (3 / 4)
- Cosine Theta = 90 degrees
