NOTES:
When both arithmetic sign and exponents are used in the same expres. s ion. the exponent is
evaluated
before
the siyn.
Example: - 5 " 4 is evaluated to -625 instead
of
625
Calculations \vithin parentheses will be evaluated first. In expressions with several "layers"
of parentheses. catculations
stare
with thr. innermost pair and proceed to the Ol1termost pair of
parentheses.
