interesting math stuff

recently received an email on kids maths "solutions" saw many of those b4, but never managed to get the actual copy, haha lemme share a few with u all...

(it may not look as hilarious as i type it out, but u shd get the idea nevertheless)

qn: Expand (a + b)^n <-- read as (a + b) to the power of n

solution: (a + b)^n = (a + b)^n = (a + b)^n = (a + b)^n <--- expanded solution


qn: /
/
x / 4
/
/___
3

find x.

the student solution is... he circled the X and say, "there it is!" -_-


qn: evaluated 1/n Sin X

solution: 6

how he/she get this is realli innovative... 1/n sin X <-- n and n cancelled, therefore,
1/n sin X = 1/1 si X = 1 six = 1 (6) = 6


qn: evaluated sqrt2/2
solution: one sqrt sign -_- cuz 2 and 2 cancel of, left one sqrt nia... -_- -_- -__-!!!


after reading this, i conclude tat kids nowadays are real smart.. my times, some of us, most fierce ones, dono how to do, at most draw one smiley face.. nowadays kids realli innovative.. this kinda solution oso can come up.. especially tat six question.. kaoz... his expansion is even more difficult than the actual solution.. kudos and salute to this chap man..
