As earlier mentioned on this blog, and as we have promised all our prospective candidates for 2017 WAEC runs,we have finally compiled all the signs and symbols that will help you in Mathematics,Physics and Chemistry and we have also

interpreted them the way it will be easy for you to understand while writing WAEC , so that you wont go to the hall and start messing up,thereby wasting the efforts we have made towards giving you the best to make sure that you smash A's in 2017 WAEC.

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
