Select a problem set to work on, and Get A Hard Copy!  You will be glad you did.

Select a problem to work on and “Get Problem”.

 

 

Display Mode:

Text: This will be disabled soon.

Formatted-text: Good for slow connections. Uses normal characters to display math.  The problem is that large or complex math expressions may not display well.

Typeset: Default mode.  Math symbols are images.

 

You enter the answers using calculator syntax: +,  -, * for multiplication, / for division, ^ for exponents, sqrt for square root (or use fractional powers), abs for absolute value. The program understands that spaces means multiply as well:  2 x is the same as 2*x.

Preview Answers to make sure the order of operations and parenthesis are doing what you think!

 

 

 

The program displays

1. your answer.
2. parsed.  This is how the computer read your answer.
3. value.  This is your answer evaluated by the computer.
4. a typeset picture.  The computer displays your answer in a more readable form, for you to check and make sure all is correctly entered.

 

 

Here, the point of the problem is to see if you can get the correct number, so the program won’t evaluate it.  That is why the error message “Invalid number format”.  The default behavior is to take any input, evaluate it, and submit that number (or expression).
