OMPT digital calculator

You are not allowed to use your own calculator

During the test,
you will automatically gain access to our digital calculator, which is pictured on the left.

When practicing,
you can use your own four-function calculator. To ensure you are well-prepared for the exam, please make sure you don't practice with functionalities our digital calculator does not have.

Calculator functions
• BS stands for Backspace, which means "erase the last digit"
• CE stands for Clear Entry, which means "erase the last number".
• CA stands for Clear All, which means "reset the calculator" and will erase everything as well as clear everything in memory (M+)


The exam questions are chosen such that they can all be answered with a four-function calculator. If trigonometry is an exam topic for you, please make sure you know the trigonometric functions of 15, 30, 45, 60, and 90 degrees by heart.
