• Basically, calculations are performed from left to right.
• Calculations enclosed in parentheses are given priority.

Note
• If a calculation contains a negative value, you may need to enclose the negative value in
parentheses. If you want to square the value –2, for example, you need to input: (–2)
2
. This is
because
x
2
is a function preceded by a value (Priority 2, above), whose priority is greater than
the negative sign, which is a prefix symbol (Priority 4).
