Easy level

This level has a single operation per question and the terms are at most 4 digits (including decimals). All answers have 4 digits or less. This is (much) simpler than a real trading test. If you want you can also try this level as a test (posts to !) or set up a custom exercise.

Medium level

This level has a maximum of 4 operations per question and all terms are at most 5 digits including the decimal part. All answers have 5 digits or less. This is about the level of some trading tests. If you want you can also try this level as a test (posts to !) or set up a custom exercise.

Hard level

This level has a maximum of 6 operations per question and all terms are at most 6 digits including the decimal part. All answers have 5 digits or less. This is beyond the level of most trading tests. If you want you can also try this level as a test (posts to !) or set up a custom exercise.

In practice mode the answers are selectable on the same page and no scoring will be done. In test mode you need to click a "Finished" button and your score will be calculated.

# Questions
Term & answer sizes
Max term length	(total # of digits, including fraction)
Max term decimal length	(# of digits after ., if variable is a double)
Max answer length	(total # of digits)
Max answer decimal length	(# of digits after ., if used)
Operations
Min operations
Max operations

Variables
Integer
Double	(This includes floats)
Use negative values for variables
Operators
Add (+)
Subtract (-)
Multiply (*)
Divide (/)
Optimizations
Optimize solvability	Limits complexity in some situations.
Prevent too simple	Guarantee operator changing & no arbitragable values.

Scoring

You get one point for every correct answer. Deduct one point for each error. If you skip a question or run out of time in a timed test, all following questions are not used in your score. Time yourself to 6 seconds per question. Generally you need to pass 55 out of 80 questions or ~70% of the maximum score, but higher is always better.

Manual

The answer to the test will be printed right next to it in the site's background color. You can use CTRL+A, Command+A or use the mouse to select all text on this page.
