**Calculator**

An on-screen calculator is provided during the test, but use it sparingly. Here's what it looks like:

As you can see, there are a limited number of basic functions available. One neat feature is that you can transfer a particular calculation from the calculator to the answer box by clicking the Transfer Display button.

**Note:** The calculator uses the standard order of operations when performing multiple operations, so it does not necessarily perform operations from left to right. The order is **P**arentheses, **E**xponentiation, **M**ultiplication and **D**ivision (from left to right), **A**ddition and **S**ubtraction (from left to right). This is often remembered by the acronym **PEMDAS**. So, if you enter 2 - (3 x 4) and click the equal symbol (=), the calculator will multiply the 3 and 4 and subtract the result from 2, giving the answer -10.
