Hi,
do they have the dolphin book for sec 2? Intend to get one to drill my son this June! -
sundaymorning:
Yes. Casio is good to build strong foundation
Yeah casco is good !SZ Venture:
you can try the casco mathematics tutor, though is for express students. but the difference between express & NA is just that NA takes a longer time to finish the topics.
ultimately, they take the same O level paper. -
Hi,
In case you are looking for Casco Maths books, I have 3A & 3B to let go as well.
Pls PM or e-mal to [email protected] if keen. -
Mr Tan’s monthly savings (S) is directly proportional to the square root of his monthly income (I). His income in January and February 2011 is $3600 and $2500 respectively. His savings in January is $80 more than in February. Find the amount he saved in January 2011.

S ∝ √I
S=k√I
January's savings ,
S(J)=k√3600 =60k
February's savings,
S(F)=k√2500 =50k
His savings in January is $80 more than in February,
S(J) - S(F) = 80
60k - 50k = 80
10k = 80
k = 8
S = 8√I
S(J) = 8√3600 = 480
the amount he saved in January 2011 is $480 -
Thanks!!

Algebra Q
Subtract 18x³ - 8x – 12 from 6x ( 2x² - 3)
My answer is different from the teacher, so need a third party (experts here) to prove me wrong. :oops:
Thanks.
