# Formulae with Numerical Codes for Values

This is an explanation to one of the other methods that students generally use in problem solving.

If too many modes would distort your understanding, it is better advised to avoid reading this. The only reason it is being given is to make you aware of all the possibilities in the learning process.

## The pit fall

We have to remember the variances based on the order number attributed to the calculated values.

The value calculations are the same as the values in the working table we prepare. Thus it would be fool proof if we are able to remember the relations in the formula as abbreviations representing values rather than the number assigned for values.

 MCV MPV MQV/MUV MMV MYV/MSUV = = = = = 1 − 2 3 − 2 1 − 3 4 − 3 1 − 4 ~ SC(AO) − AC ~ SC(AQ) − AC ~ SC(AO) − SC(AQ) ~ SC(AI) − SC(AQ) ~ SC(AO) − SC(AI)

If we are to find out the variances for individual materials, then multiple calculations of this sort have to be made once for each material. The working table format would be more convenient to derive all the information needed.

If we understand the logic behind the formulae, we don't even need to mug up the formulae. We can recollect or derive them on the fly. Try working out all the problems with the same set of formulae.
