# CSET Foundational-Level Mathematics Test

In order to teach Foundational-Level Mathematics in the state of California, teacher candidates are required to take the CSET: Foundational-Level Mathematics exam which is actually Subtest I and Subtest II of the CSET: Mathematics exam. Each subtest must be registered for and taken individually. The computer-based subtests each include thirty-five multiple-choice questions and three constructed-response questions. You will have a total of two hours and thirty minutes for each subtest. A score of 220 is required to pass each subtest.

Subtest I (test code 211) consists of two content domains. The Number and Quantity domain is comprised of real and complex number systems and number theory. These questions verify your knowledge of the real number system and its subsets, your ability to perform operations, express real numbers in various forms, basic properties of natural numbers, the principle of mathematical induction to prove results in number theory, the Euclidean Algorithm, and the Fundamental Theorem of Arithmetic. The second content domain of subtest I is Algebra. The Algebra domain covers algebraic structures, polynomial equations and inequalities, functions, and linear algebra. A broad range of topics are included such as properties of real and complex numbers, factoring, manipulation of algebraic expressions, the Fundamental Theorem of Algebra, the Rational Root Theorem, the Conjugate Root Theorem, the Binomial Theorem, the Factor Theorem, the quadratic formula, polynomial inequalities, analyzing general properties of functions, applying arithmetic operations on functions, modeling, problem solving using nonlinear functions, vectors, matrices, analyzing properties of proportional relations, lines, linear equations, and graphs.

Subtest II (test code 212) also consists of two domains. The Geometry domain measures knowledge of Plane Euclidean Geometry, Coordinate Geometry, Three-Dimensional Geometry, and Transformational Geometry. The second domain, Probability and Statistics, involves permutations and combinations, finite probability, conditional probability and independence, computing and interpreting the probability of an outcome, the use of normal, binomial, and exponential distributions in solving and interpreting probability problems, and the calculation of expected values and using them in problem solving and evaluation. The Statistics questions include computing and interpreting means, medians, quartiles, range, interquartile range, and standard deviation of discrete and continuous distributions. You will need to bring your own graphing calculator for this subtest. A list of approved models is available on the testing website.

## CSET Foundation-Level Mathematics Test Answers

The sum is written as:
2222
+ 303
3030
The sum of 2 and 3 equals 5, which must be represented as a 10. In the base-5 number system, a number cannot contain any 5’s. The 1 of each 10 is carried to the next column to the left.

The percent increase is represented as (1100-800)/800, which equals 0.375 or 37.5%.

The set of integers is contained within the set of rational numbers, and is hence, a subset. A rational number may be written as the ratio, a/b, where a and b are integers and b ≠ 0.

The situation may be modeled by the system
4x+3y = 9.55
2x+2y = 5.90
Multiplying the bottom equation by −2 gives
4x+3y = 9.55
-4x-4y = -11.80
Addition of the two equations gives -y = -2.25 or y = 2.25. Thus, one box of crackers costs \$2.25.

The derivative of an equation of the form y = ax^n is equal to (n*a)x^(n-1). So the derivative of y = 9x^2 is equal to (2*9)x^(2-1) or 18x
