i am horrible at maths need help asap

With algebra you are learning problem solving-that is the process of problem solving using rules and equations. The best way to learn it is to shut out all distraction and work at it. If there is something you don't understand you may have to go back to the beginning and learn all the principals and rules that you don't understand- Algebra can be a very hard subject but it can be concord with persistence.

i want to be come mart in mathematics Specialy computation problems......pls teach me by online tutorials free....

You didn't say which part of mathematics you want to study or what is you previous knowledge.

For algebra see these courses:

On The Open University you can find even more courses and on this site you can find links to a lot of online resources for algebra (lessons, tutorials, games, problems...).

For calculus I recommend:

And if you have questions or you don't understand something you can ask here.

I hope I helped you :)

What does ker(f) in lienar algebra mean?

It seems to me that such question is well above the grade level that appears in the heading. Ker(f) comes from the English word kernel . The kernel of a homomorphism (application, not necessarily a function ) between two sets that have similar algebraic structures, is the subset of the original set (domain) the images of which are the neutral element in the target set (range). The kernel measures the degree to which a homomorphism fails to be injective.
Specific definitions exist for specifiq contexts.
I would advise you to curl up with a good book on abstract algebra and read more, with pen and paper,

Hope it helps.

Write a problem that can be evaluated by the algebraic expression x- 450. Then evaluate for x = 1325

Math & Science Grade 1-3

I don't think you can learn algebraic equations in a low grade. It is simple enough if you just solve by hand or by a calculator.

Solve for y, when x = 1325.
x - 450 = y

1325 - 450 = y
y = 875
