The SAT Subject Test in Mathematics Level 1 (formerly known as Math I or MathIC (the "C" representing the use of a calculator)) was the name of a one-hour multiple choice test given on algebra, geometry, basic trigonometry, algebraic functions, elementary statistics and basic foundations of calculus [1] by The College Board.
The College Board stated that a calculator "may be useful or necessary" for about 55-60% of the questions on the test. The College Board also encouraged the use of a graphing calculator over a scientific calculator, [7] saying that the test was "developed with the expectation that most students are using graphing calculators."
Thirteen of the questions on the math portion of the SAT (about 22% of all the math questions) are not multiple choice. [58] They instead require the test taker to bubble in a number in a four-column grid. All questions on each section of the SAT are weighted equally. For each correct answer, one raw point is added. [59]
In computer science and formal methods, a SAT solver is a computer program which aims to solve the Boolean satisfiability problem.On input a formula over Boolean variables, such as "(x or y) and (x or not y)", a SAT solver outputs whether the formula is satisfiable, meaning that there are possible values of x and y which make the formula true, or unsatisfiable, meaning that there are no such ...
In the late nineteenth century, elite colleges and universities had their own entrance exams and they required candidates to travel to the school to take the tests. [10] To better organize matters, the College Board, a consortium of colleges in the northeastern United States, was formed in late 1899 to establish a nationally administered, uniform set of essay tests based on the curricula of ...
Graph coloring [2] [3]: GT4 Graph homomorphism problem [3]: GT52 Graph partition into subgraphs of specific types (triangles, isomorphic subgraphs, Hamiltonian subgraphs, forests, perfect matchings) are known NP-complete. Partition into cliques is the same problem as coloring the complement of the given graph.

Some questions on the SAT and PSAT are free-response, as opposed to multiple-choice, and require a test taker to provide the numerical answer. Possible answers for grid-in questions are never negative and range from 0 to 9999. Fractions and decimals may also be entered using the symbols in the grey background.
