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.

Yeah casco is good !

Yes. Casio is good to build strong foundation

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

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.
