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:
