ISEE Math Review – System of Linear Equations: Elimination and Substitution

So far, you have mostly been solving for a single variable in an equation or placing one variable in terms of the others. However, you will likely face questions asking you to solve for more than one variable, and these questions will likely be about linear equations. A linear equation simply refers to an [...]

ISEE Math Review – Factoring Algebraic Expressions

Since we can multiply algebraic expressions we can factor them out. While the process of factoring is different than using a factor tree, the concept is the same. You are looking for what parts make up the whole algebraic expression. Think of factoring as the reverse of multiplying algebraic expressions. Factoring out algebraic expressions [...]

ISEE Math Review – Multiplying Polynomials

Algebraic expressions are not solely made up of coefficients and a single variable. Algebraic expressions can be made up of multiple terms, which are either added or subtracted from each other. These terms can include several distinct variables, their coefficients, and known quantities called constants. Depending on their number of terms, algebraic expressions can [...]

ISEE Math Review – Operations on Algebraic Expressions

In a nutshell, Algebra is arithmetic using known and unknown quantities. These unknown quantities are called variables and are represented as a letter (x) or a symbol. You have already evaluated some algebraic expressions by substituting certain values for some or all of the variables within the expression. Now, let’s apply what we [...]
