If you count left 7 from 5 on the number line where would you be?

Right click the picture and click "Copy Image Location" tell me when you did that.

Let me know when you have uploaded the picture from your machine to imgur.com

I think you just posted the question without using a picture.

Once you have uploaded to that site it is a simple matter to put it into your post.

Do you have a picture you want to post?

Yes, http://imgur.com/

You can upload picture to that site and then to your posts.

Hi Srikantan;

You did not answer the two questions I gave you.

You can upload a picture using imgur.com.

You can also use Latex.

Glad it helped. Welcome to the forum.

Take the integers 0 ,1,2,3,4 and plug them into y one at a time in

Then plug those same integers into x one at a time in

and tell me what you get.

Hi;

Textbooks all have one mother. Two million years ago some hairy ape-man or man-ape depending on which anthropologist you talk to, wrote the first one. It was written on clay tablets and weighed about 2500 tons. Since then all authors have read that book and created their own condensed version of it. Essentially, they read a very big ( and heavy ) book and wrote a smaller and lighter one. Since that mother of all math textbooks was an utter bore the children can be not be much different.

I like Martin Gardner books.
