Simplifying numeric expressions
Webb7 apr. 2024 · Factoring is a way to simplify expressions by removing factors that are common across all the terms in the expression. To start, find the greatest common factor that all of the terms in the expression share - in other words, the largest number by which all the terms in the expression are evenly divisible.

WebbPurplemath. We have three basic rules for combining exponents: an · am = an+m. \small { \dfrac {a^n} {a^m} = a^ {n-m} } aman =an−m. ( an) m = anm. However, when simplifying expressions containing exponents, don't feel like you must work only with, or straight from, these rules. It is often simpler to work directly from the meaning of exponents.

WebbIn Unit 3, seventh-grade students bring several prior skills together to manipulate expressions into different equivalent forms. In the preceding unit, students operated and reasoned with positive and negative rational numbers. In this unit, they use these new skills to expand, factor, add, and subtract numerical and algebraic expressions.
