WebbIn this lesson you will learn about multiplication properties and their significance. For example, that a × b = b × a or that a (b + c) = ab + bc. You will learn how distributive property is used to simplify algebraic expressions. This property is also often used to solve equations. For example, when solving an equation 2 (3x – 1) = 10 the ...
