Scientific calculators are used widely in situations that require quick access to certain mathematical functions, especially those that were once looked up in [[Mathematical table|mathematical tables]], such as [[trigonometric functions]] or [[Logarithm|logarithms]].  They are also used for calculations of very large or very small numbers, as in some aspects of [[astronomy]], [[physics]], and [[chemistry]].

They are very often required for math classes from the [[Junior High School|junior high school]] level through [[college]],<ref>{{Cite book |url=https://books.google.com/books?id=qXcKxLC6qE8C |title=The State of Mathematics Achievement: NAEP's 1990 Assessment of the Nation and the Trial Assessment of the States |date=1991 |publisher=The Center |isbn=978-0-16-033144-2 |language=en}}</ref> and are generally either permitted or required on many [[standardized test]]s covering math and science subjects;<ref>{{Cite book |last1=Review |first1=Princeton |url=https://books.google.com/books?id=oiiw4CCNm9gC |title=Cracking the SAT Math 1 & 2 Subject Tests,: 2013-2014 Edition |last2=Spaihts |first2=Jonathan |date=2013-03-05 |publisher=Random House Information Group |isbn=978-0-307-94554-9 |language=en}}</ref> as a result, many are sold into educational markets to cover this demand, and some high-end models include features making it easier to translate a problem on a textbook page into calculator input, e.g. by providing a method to enter an entire problem in as it is written on the page using simple formatting tools.
