BASIC MATH OPERATIONS
Your calculator uses standard chaining
logic, which simply means that you enter
your first value, the operator (
+
,
–
,
x
,
÷
), the second value and then the Equals
sign (
=
).
A.
3 + 2 =
5.
B.
3
–
2
=
1.
C.
3
x
2
=
6.
D.
3
÷
2
=
1.5
This feature also makes the calculator
simple to use for dimensional applications:
Adding and Subtracting Strings of
Dimensions
Add the following measurements:
• 6 Feet 2-1/2 Inches
• 11 Feet 5-1/4 Inches
• 18.25 Inches
Then subtract 2-1/8 Inches.
