Powers or exponents refer to multiplying the same number to itself a certain number of times, and the same is true for variables and algebraic expressions. The exponent will be located in the upper right hand corner next to the number and will be much smaller than the number (called superscript). When the power [...]
Number lines are used to visually represent the relationships between integers, fractions, and decimals and to show how mathematic operations work in these relationships. Some number lines are shown with arrows pointing in opposite directions on either end of the line to designate a continuity of sequence in positive and negative numbers. The number line [...]
Word problems can be some of the most difficult types of questions on any test. You have to understand precisely what the question is asking you and what relevance the quantities have to one another. For Arithmetic Word Problems, you will not really have to worry about creating algebraic expressions in order to answer [...]
Operations are the actions taken to solve math problems: addition, subtraction, multiplication, division, grouping (placing values in parentheses), and exponentiation (multiplying the same number to itself a certain number of times). Order of Operations was developed to make sure operations in a problem are completed in a particular order to achieve the correct result. [...]
Math is filled with theorems, axioms, and properties. Though the following properties may seem simplistic, the ISEE will couple these properties with difficult concepts, such as algebraic functions. Reflexive Property A value is equal to itself. x = x Examples 17 = 17 y = 400 Symmetric Property Equal values may be placed on [...]
The ISEE Upper Level is the private schools admissions test for students applying to grades 9 through 12.

The Educational Records Bureau (ERB) makes only one near full-length practice test available for the ISEE Upper Level. Available as a free PDF download on its website, this is the only official practice test. However there at least two major downsides to this test. First, it is only 140 questions in length whereas [...]

The entirety of the ISEE Mathematics Achievement test is comprised of word problems, and much of the Quantitative Reasoning section is as well. Given that the Mathematics Achievement Test is the longest test on the ISEE, and the Quantitative Reasoning test is generally considered the most challenging, it's a good idea to improve your [...]
