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 sim-
ple to use for dimensional math.
Adding or Subtracting Dimensions
1) You can add or subtract two numbers
when the first value entered is labeled
with units of measurement and the
other is just a whole number (no units
of measurement).
2) You can add or subtract numbers
whose units of measurement are within
the same convention. For example,
you can add or subtract kg and
pounds.
3) You cannot add or subtract two num-
bers of different conventions, except
for weight and volume.
