Simple Arithmetic Calculations in ALG Mode
In ALG mode, any simple arithmetic calculation involves two numbers and an
operation — addition, subtraction, multiplication, or division. To do such a
calculation on your hp 12c platinum, you tell the calculator the first number, then
the operation to be performed, and then tell the calculator the second number. The
answer is calculated when the equals key (
}
) is pressed.
For example, to calculate 21.1 + 23.8, do the following:

order you enter them. Note that if you have just pressed

, there is no need to
press

before starting a new calculation – the
}
key will have completed
any pending operations.
