maths questions iq is my worst problem. Can any one help me understand it? I am a novice at it. What book or other resource do you suggest for beginning this subject?

You might want to take a look at Algebrator. I bought it some time back to help me with my Basic Math course and I can say that it was really a good choice . There are so many examples provided which you can go through. You can also try out the questions related to trigonometry and roots by just typing them in. Algebrator provides detailed description to the problems which helps to make difficult concepts very clear. I would say that this program is absolutely the best that money can buy.

Algebrator is a remarkable product and is certainly worth a try. You will also find quite a few interesting stuff there. I use it as reference software for my math problems and can say that it has made learning math much more enjoyable.
