Algebra

apsara60 @apsara60 (6610) • Israel 30 Jan 07

Is algebra really useful anywhere. What do we learn by learning Algebra (all those x+y and a+b )... I did like it and I got good marks, but I just don't know where it is used. Please let me know if you all know. Thanks.

Do you think basic manners should be taught in the schools or home?

Bee1955 @Bee1955 (3882) • United States 27 Feb 07

I overheard a lady in the library the other day ranting about how her child is ignorant of using manners because he is so disrespectful at home. Then she blamed the child's school for "not doing their job". STOP! I mean, COME ON!...

rodmac If good manners and behaviour are fostered in a good stable loving home the child will carry that culture wherever he/she goes. Teachers' responsibility ought to be 'polishing' the rougher members of their class/group and chastising anyone who does not meet...

simultaneous equation.

zugedanit @zugedanit (1958) • Philippines 16 Feb 07
