Scientific calculators are extensively employed in circumstances where quick access to certain mathematical functions is required, particularly those that were previously looked up in mathematical tables, such as trigonometric functions and logarithms. They’re also employed in astronomy, physics, and chemistry to calculate extremely large or extremely small values.

They are frequently required for math classes from junior high to college, and they are generally permitted or required on many standardized tests covering math and science subjects; as a result, many are sold into educational markets to meet this demand, and some high-end models include features that make it easier to translate a problem from a textbook page into a calculator in real time.
