• Operations with the same precedence are performed from
left to right, with operations enclosed in parentheses per-
formed first. If parentheses are nested, the operaitons en-
closed in the innermost set of parentheses are performed
first.
• Registers L
1
through L
6
store operations. There are six re-
gisters, so calculations up to six levels can be stored.
• Each level can contain up to three open parentheses, so
parentheses can be nested up to 18 times.
• Example: The following operation uses 4 levels and 5
nested parentheses.
