(2) Parentheses Calculation Priority Sequence
Expressions enclosed inside parentheses are always given priority in a calculation.
Example 1
Abaa-(c+d)
*ew
Example 2
• A multiplication sign immediately in front of an open parenthesis can be omitted.
A(h-c)(i+f)
w
• Any closing parentheses at the end of a calculation can be omitted, no matter
how many there are.
Parentheses are always closed in the operation examples presented in this manual.
(3) Negative Values
Use the - key to input negative values.
Example
Afg*-bc/
-c.fw
(4) Exponential Expressions
Use the E key to input exponents.
Example
Ae.fEhf*-c.d
E-hjw
