[renegade4141]

vids are good but i hav a feeling these comments are planted

[mathstutorbiz]

why do you say that? the only comments by mathtutor will have the maths tutor user name, like this one. the only comments removed are those trying to make a link with other web sites, usually shall we say rude web sites!!

[xj4k3x]

i can see renegade4141 point its not hard to make another acount or get people you know to make good coments to promote your website

[mathstutorbiz]

True, but I don't.

[coolflyin17]

i wish my advanced algebra teacher could teach like this

i usually have no idea what hes talking about

[rubent100]

funny how they say "not" instead of zero

[Anbaransu88]

actually u do not need to draw the graph out to find the angle..it is actually very simple equation...jz use the quadrat theory..tats simple instead of drawing the graph which is rather wasting time =.=

[mongomitderbongobong]

ridiculous discussion. Get a life people.
