### Quick Answer

**In math, expanded form can refer to any type of expression, equation or notation that is completely broken down into its individual parts.** Expanded form is commonly used in teaching students place value and factoring.

### Full Answer

In discussion of place value, expanded form is when a number is broken down into each place value with an addition sign placed between each number. For example, 356 would be 300+50+6 in expanded form. When an expression is factored, it changes the expression into expanded form. x^{2}-4 would factor into the expanded form of (x-2)(x+2). The expanded form of quadratic equations is often more useful in graphing than the standard form.
