ISEE Math Review – Circles

A circle is a perfectly round geometric shape which you will see again and again in your studies of math concepts. You will need to have an understanding of its diameter, radius, circumference, area, arcs, and sectors. You will also work with objects that are tangent to a circle and what that means. Diameter [...]

ISEE Math Review – Polygons: Angles, Perimeter, and Area

Polygons are two‐dimensional shapes that are formed by three or more straight sides. You will be analyzing these geometric figures to find the total degree value of a polygon, the perimeter of a polygon, and the area of a polygon. The perimeter is the measurement of the sum of the side lengths of a [...]

ISEE Math Review – Triangle Types and Rules

Triangles are those handy‐dandy three‐sided polygons with which mathematicians have done so much work, particularly the right triangle. The most important thing to remember about all triangles is that the sum of their interior angles is 180°. Again, the sum of the interior angles of any triangle is 180°. Once more, the sum of [...]

ISEE Math Review – Geometric Notation

Geometry is the branch of mathematics that encompasses the properties and relationships of shapes, such as points, angles, and solid figures. Like every other branch of mathematics, Geometry comes with its own set of notations. Types of Angles  An angle is formed when two rays share the same endpoint, which is called the vertex [...]

ISEE Math Review – Matrices

A collection of numbers (called entries) contained within a pair of [ ] brackets is called a matrix. A matrix is labeled by a variable, which is usually a capitalized letter. In a sense, matrices are like sets of data, except that a matrix is made up of rows and columns of data as [...]

ISEE Math Review – Transformations of Functions

A transformation simply refers to moving the graph of a function around: If you want to move the line graph of y = 2x + 1 to the left or right, you increase or decrease the input. If you want to move the line graph of y = 2x + 1 up or down, [...]

ISEE Math Review – Domain and Range

The set of all possible inputs for a function is called the domain, and the inputs fall on the x‐axis in a graph. The set of all possible outputs for a function is called the range, and the outputs fall on the y‐axis in a graph. If the domain has an input that is [...]

ISEE Math Review – Function Notation

With so many formulas and equations to know and use, computations can become confusing when you must use several formulas and/or equations for the same problem. Function notation was developed to help differentiate between distinct equations and formulas, which are all considered functions. A function is a correspondence, or relation, between two sets of [...]
