Circled Operators

There are several circled operators that are supported by the equation editor, but none of the symbols can be entered via the braille terminal at present. However, you can still enter the symbols from the editor’s Circled Operators palette, the arguments in the full cells. If your braille display includes routing keys, simply press the routing key above the full cell you wish to move to, or use the left/right arrow keys.

Exercises

Using the equation editor's Circled Operators palette, enter the following symbols 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 Circled plus y
• X circled times (2 circled plus x^2)
• 2 circled times 3
• 2 circled equals 3
• x circled left arrow y
