Subscripts

The subscript indicator (dots 56) is used to enter a subscripted variable or number.

When typing a subscripted expression, the baseline indicator (dot 5) is used to terminate the subscript and return to the baseline (after the subscript) to allow additional input after the subscripted expression.

When a subscript is applied to more than one symbol, be sure that the entire expression contained in the base is selected (underlined with dot 8) before typing the subscript indicator to ensure the subscript is applied properly.

When the base or the subscript involves more than a single symbol, parenthesies may be used for clarification.

Exercises

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.

• S sub 1
• C1 + c2 = y
• S sub n, T sub 2
• x sub 1 sub sub 2 sub sub sub 3 ...
• x sub 2 sub 3 sub y
