# Instructions

### To Start a Test:

;start();, and press enter.

*All input is entered by pressing Enter>*

`"Mike"`.

`"2070779"`.

`"2P08-1"`.

*DURING THE TEST:*

- When you type a mathematical expression as your answer,
use * for multiplication, ** for exponentiation,
/ for division and parentheses where appropriate.
An answer is typed in form of a sequence of letters, digits and symbols.

Example: To input1 2 - x 2

type:1/2*x**2

followed by`ENTER`. If your input is longer than one line then just continue typing and press the`ENTER`key only at the end when you want to submit the answer. - Some operations have a higher priority than others. For example,
typing
`3+x * 4+y`would be interpreted as`3+(x*4)+y`because`*`is applied before`+`even though the`+`appeared before`*`in the formula. Highest priority has the`-`sign in front of a number or in front of a variable name followed by`**`, then`*`and`/`, then`+`. As`*`and`/`have the same priority, whichever comes first (on the left) is executed first. For example,`1/x*y`will be interpreted as`(1/x)*y = y/x`and NOT as`1/(x*y)`. Hint: If one is not sure it is always safest to type all brackets. - Your submitted answer will be displayed in a more graphical
setting (e.g. with raised exponents) and you are asked for confirmation.
Pressing
`y`and`ENTER`confirms your input, any other input will mean that you do not confirm and you are asked to re-submit an answer. - For special functions use the following names, just like in
other languages:
`SIN, COS, TAN, SINH, COSH, TANH`and`SQRT`for the square root. The logarithm to basis`e`is called`LOG`. - Lists are enclosed in {}. For example, the list of numbers 1,2,3 would be {1,2,3} .
- Some questions need pencil and paper to solve the problem first before typing in the answer.
- For some questions only the value of the solution matters and not its
form. Such expressions can be input in any form, for example,
`1/x`or`x**(-1)`or`x/x**2`. For other questions the form of the input matters. For example, if`x/x**2`shall be simplified then`x/x**2`is not good enough as an answer which should be given in the form`1/x`or`x**(-1)`.

*AT THE END OF THE TEST:*

If you want to be sent an email with a transcript of the test then
enter your email address enclosed in " " else enter "no".
Afterwards you can close the browser window or click the refresh
button to re-do a test.

*GOOD LUCK!*
