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

I have been stuck for some time with simultaneous equations. I can do simple ones but as soon as I do harder ones I get stuck. I know how to start them off but it's just getting down to the actual x and y.

rodmac Here is a quick lesson in simultaneous equations:- Equ 1 :2x + 3y + 8 = 34 Equ 2 :4x - 2y + 9 = 13 Call each equation a number & make the coefficient of one variable, eg 'x' the same. So Equ 1 multiply by 2 becomes 4x + 6y + 16 = 68 : Equ 3 combine...
