Helpful Hints & Links for TSI Math Placer
For the math portion of the TSI exam there are three different types of questions that you can expect.
· The first type involves operations with integers, rational numbers, and includes computation with integers and negative rationales, the use of absolute values, and ordering.
· The second type involves operations with algebraic expressions using evaluation of simple formulas and expressions, and adding and subtracting monomials and polynomials. Questions involve multiplying and dividing monomials and polynomials, the evaluation of positive rational roots and exponents, simplifying algebraic fractions, and factoring.
· The third type of question involves translating written phrases into algebraic expressions and solving equations, inequalities, word problems, linear equations and inequalities, quadratic equations (by factoring), and verbal problems presented in an algebraic context.
