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 Parentheses, Exponentiation, Multiplication and Division (from left to right), Addition and Subtraction (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.
