AxB ..... 3=C
is interpreted as A x B3
To raise A x B to the 3rd
(AxB) ..... 3=C.
A +B+C= 12
is interpreted as A
12. To divide the sum
B by C, enter
CHG <T +12: A-6 )-,'2,
the Solver evaluates the argu-
6, computes the value of the function, and
then squares the function value .
• You cannot use parentheses for implied multiplication. For exam-
ple, the expression
P(1 - F)
must be entered as P x ( 1 - F ), with the
x operator inserted between P and the parenthesis.
