### Summer Suggestion for Students

If you have got some days off in summers then I would recommend learning typing in proper fashion for a few days and then practice what you have learnt subsequently. I think 15 days or so will get you started in the right direction but later on you will have to carry on with what you have learnt and will have to resist the temptation of going back to, "one finger style". The way computers are becoming part of life in learning and in any profession for that matter, this will help you a lot now and in future. This could perhaps be one of the great use of holidays.

### Sum of the coefficients in the expansion of $(x+y)^n$ ....

If the sum of the coefficients in the expansion of $(x+y)^n$ is 4096, then the greatest coefficient in the expansion is _ _ _ _ . Solution $C_0 + C_1 + C_2 + C_3 + ......................... + C_n =4096$ $\therefore 2^n = 4096 =2^{12}$ $\Rightarrow n = 12$ Greatest coefficient = ${}^{12}{C_6} = 924$
