1 Order of execution moves from 1 to 10 with 1 executing first. When operators have the same order of execution number, the
order for their execution within an expression is from left to right.
The parentheses around the 6 + 3 tells the 1775-S4B scanner to execute the
contents of the inside parentheses first. Thus, the expression returns 18 as
the answer.
If two or more operators with the same level appear in an expression, the
1775-S4B scanner executes them in the order that they appear on the
statement line. For example:
(6 + 3 - 2)
The 1775-S4B scanner adds 6 and 3, then subtracts 2, and returns 7 as the
answer.
The following sections explain the functions of these operators.
