Some of the computations you'll need to perform to answer a question on the Elementary Education: Mathematics and Science CKT tests are somewhat time-consuming, such as long division or finding square roots. For such computations, you can use the calculator provided with your test.

Although the calculator can shorten the time it takes to perform some computations, keep in mind that the calculator provides results that supplement, but don’t replace, your knowledge of mathematics. You’ll need to use your mathematical knowledge to determine whether the calculator's results are reasonable and how the results can be used to answer a question.

## General guidelines for using the on-screen 4-function calculator

• Most of the questions don't require difficult computations, so don't use the calculator just because it's available.
• Use it for calculations that you know are tedious, such as long division; square roots; and addition, subtraction or multiplication of numbers that have several digits.
• Avoid using it for simple computations that are quicker to do mentally.
• Avoid using it to introduce decimals if you are asked to give an answer as a fraction.
• Some questions can be answered more quickly by reasoning and estimating than by using the calculator.
• When you use the calculator, estimate the answer beforehand so you can determine whether the calculator's answer is reasonable. This may help you avoid key-entry errors.
