# THE MATHEMATIC SECTION

 Time Content Item Types Score 70 min. (two 25-min. sections and one 20-min. section) Number and operations; algebra and functions; geometry; statistics, probability, and data analysis Five-choice multiple-choice questions and student-produced responses 200-800

Overview
The SAT will include expanded math topics, such as exponential growth, absolute value, and functional notation, and place greater emphasis on such other topics as linear functions, manipulations with exponents, and properties of tangent lines.
Important skills formerly measured in the quantitative comparison format, such as estimation and number sense, will continue to be measured through the multiple choice and student response (grid-in) questions.

CAN I USE THE CALCULATOR
Yes. Students can use a four-function, scientific, or graphing calculator. The College Board recommends that students use a calculator at least at the scientific level for the SAT, although it's still possible to solve every question without a calculator.

MATH REVIEW
For the new SAT, the mathematics content level of the test will be raised to include more advanced topics. The following math concepts will be covered beginning with the March 2005 test.

NUMBER OF OPERATION
* Arithmetic word problems (including percent, ratio, and proportion)
* Properties of integers (even, odd, prime numbers, divisibility, etc.)
* Rational numbers

* Sets (union, intersection, elements)
* Counting techniques
* Sequences and series (including exponential growth)
* Elementary number theory

ALGEBRA AND FUNCTIONS
* Substitution and simplifying algebraic expressions
* Properties of exponents
* Algebraic word problems
* Solutions of linear equations and inequalities
* Systems of equations and inequalities
* Equations of lines
* Absolute value
* Direct and inverse variation
* Concepts of algebraic functions
* Newly defined symbols based on commonly used operations

GEOMETRY AND MEASUREMENT
* Area and perimeter of a polygon
* Area and circumference of a circle
* Volume of a box, cube, and cylinder
* Pythagorean Theorem and special properties of isosceles, equilateral, and right triangles
* Properties of parallel and perpendicular lines
* Coordinate geometry
* Geometric visualization
* Slope
* Similarity
* Transformations

DATA ANALYSIS, PROBABILITY & STATISTICS

* Data interpretation
* Statistics (mean, median, and mode)
* Probability
