V30-RA SCIENTIFIC CALCULATOR
General Information
Your Victor V30-RA Scientific Calculator is made with 40% recycled plastic and an antimicrobial agent that prevents the growth of
microbes that cause odors and discoloration. The V30-RA has a large 10 digit display plus 2 digits for exponents.
Battery Replacement
The Victor V30-RA comes with two LR44 batteries which can be replaced by removing the (6) screws in the back of the unit.
Order of Operations
The Victor V30-RA uses the Algebraic Operating System or AOS to determine the order in which operations are performed. Based
on the complete equation, the calculator will use the following table to determine whether an operation is to be completed or delayed
based on its priorities.
1
st
Expressions inside parentheses.
2
nd
Single-variable functions that perform the calculation and display the result immediately.
3
rd
Permutations ( nPr ) and combinations ( nCr ).
4
th
Exponentiation and root functions.
5
th
Multiplication and division
6
th
Addition and subtraction
7
th
= / Enter closes all open parentheses and completes all operations.
Pi 3.141592653590
π
(Pi) Pi is the ratio of the circumference of a circle to its diameter. Pi carries out many digit places beyond the decimal point;
though to accurately use in a calculation most people carry it out to 6 or 7 digits.
π
= 3.141592654 on the display.
π
= 3.141592653590 is used for calculations.
