Click 'New problem' to create a new problem.
Solve it (using a paper and pencil is suggested) and enter your
answer at the top. You can either click in the text area and
type your answer, or you can use the slider (no typing required!)

Slider use: be SURE to select the element (row,column) you want to
set from among 1,1; 1,2; 1,3; 2,1; and so on. Then set the slider
as required and click 'enter'. You do not have to enter the 'size'
field, that will set itself as you work through the element choices.

When all elements are entered, click 'Check it'

When you're ready to take a test, click 'Take a Test' and login.
Proceed as before, now when you click 'Check it' your answer will
be recorded. Exactly what is recorded appears in the 'Data Logged'
box at the bottom.

When done, turn logging off, click 'Log off'.

Hint, it helps to have a 'calculator' around; most systems have an
electronic one. (In unix/linux type 'xcalc' in some window; in
Windows run 'calc'.
