# Exam review for number conversions:

First a check to make sure you know the terminology:

Matching:

The table below is in the wrong order.
Draw a line from the term on the left, to the correct base on the right.

## Now practice with conversions

Each time you click the "make new quiz" button, you'll get a different randomly generated quiz.
The actual questions on the final exam will be generated from this form.

Note that "leading zeros" and "spacing" do not affect the correctness of your answers—for example:

• In binary, 0101 and 101 are the same number.
• In binary 0010 0011, 0100011, and 100 011 are all the same number.
