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 math.
