Prev Up Next Page 129 of 800 Search internet


Consider the following lgs source text:

   ""P my page
   ""D 0 ""n 2 ""n 3 ""n 4 ""n 5
   ""D 2
   " * "
   ""D 4
   - "
   ""D 6
   " + "
   " - "
   ""B
   2 * - 3

In this case, the body reads:

2 * [- 3]

Note the charge inversion. The unary minus has higher charge than times, but there is no way it can become the principal operator.

Exercise: Enter understood parentheses in the following construct:

   - 2 * - 3

For a solution, see next page.
