Math Operations
Your calculator uses standard chaining
logic. This means that you enter your
first value, the operator (+, –, x, ÷), the
second value, then the (=) sign.
3 [+] 2 [=] 5
3 [–] 2 [=] 1
3 [x] 2 [=] 6
3 [÷] 2 [=] 1.5
This feature also makes it easier to
solve dimensional problems.
Adding Dimensions

7 [Feet] 3 [Inch] 1[/] 2 [+]
11 [Feet] 4 [Inch] [=] 18 FT 7-1/2 IN
Add 11 inches to 2 feet 1 inch:

Note: The format of the first value you enter
determines the format of the answer.
However, with the [Conv] key, you can
change to any format you want, provided
that you maintain convention.
