2.3 Use of calculator memory
A portable calculator is an extremely useful tool for a bookkeeper or an accountant. Although computers normally provide computer applications, there is no substitute for the convenience of a small, portable calculator or its equivalent in a mobile phone or tablet.
When using the calculator, it is safer to use the calculator memory (M+ on most calculators) whenever possible, especially if you need to do more than one calculation in brackets. The memory calculation will save the results of any bracket calculation and then allow that value to be recalled at the appropriate time. It is always good practice to clear the memory before starting any new calculations involving its use. (Consult your own calculator manual for its method of storing any calculation in memory as well as its instructions for clearing memory.)
Box 1 The memory function in a scientific calculator
The scientific calculator memory is particularly useful for more complex calculations in accounting. Such a calculator has a number of different memories of which the ‘M’ memory is the most commonly used in accounting calculations. Like most calculators, the ‘M’ memory is accessed using the M+ key. Only the most basic calculator is needed for this course but a scientific calculator should be strongly considered for any future study in accounting.
Activity 2 Use of calculator memory
Use the memory on your calculator to evaluate each of the following:
- 6 + (7 – 3)
- 14.7/(0.3 + 4.6)
- 7 + (2 x 6)
- 0.12 + (0.001 x 14.6)
