MATHEMATICAL 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 math, as shown in the
following examples:
