Answer 1

Click MC to clear the memory
Click M+ to add the value to memory.
Click MR to recall what is in memory. Then click =

STEPS:

1. AC to clear all

3. Click MC to clear the memory, then click M+ to add the value to memory.
4. Click AC to clear previous addition.
5. Then enter 8 - 3 and =.

And that is the way. (there are calculators with more than one memory.
