Pre-algebra

Pre-Algebra is a common name for a course in middle school mathematics. In the United States, it is generally taught between the fifth and eighth grades, although it may be necessary to take this course as early as 3rd grade if you are in the gifted program at your school. The objective of Pre-Algebra is to prepare the student for the study of algebra.

Pre-Algebra includes several broad subjects:

• Review of natural number arithmetic
• New types of numbers such as integers, fractions, decimals and negative numbers
• Factorization of natural numbers
• Properties of operations (associativity, distributivity and so on)
• Simple (integer) roots and powers
• Rules of evaluation of expressions, such as operator precedence and use of parentheses
• Basics of equations, including rules for invariant manipulation of equations
• Variables and exponentiation

Pre-algebra often includes some basic subjects from geometry, mostly the kinds that further understanding of algebra and show how it is used, such as area, volume, and perimeter.
