Good job done.
In fact remembering the log values of 2,3,5,7 is enough to find any log value .
For eg: log 20=log(4 x 5)= log4 + log5=2log2 + log5=2(0.3010) + 0.6990= 0.6020 + 0.6990 =1.3010
Actually log value of 4 according to the tables is .6021 but it differs just by 0.0001 which is really very small.
