Tables, Radiativity Diagrams

Table1

A table of this would be computer as follows

X:1,2,3,4
FX:4,6,8,10
F(X-Xbar):10,8,6,4

Table2

A table like this would be computed as follows
Particulars: maintenance,salaries &wages, Purchase of Drugs, total
Amount: 2500,1000,2000,5500
Logarithm Table

Tabulate
No:92.63, Log:1.9667
No: 2.914, Log: 0.4645
2.4312
Antilog = 269.9
Therefore 92.63*2.914=2.4312
