Thus expressions enclosed in smaller parentheses should usually be evaluated before expressions enclosed in larger parentheses. example 1 10 chapter 1 The Real Numbers Now to evaluate the expression 6 + 3 · 5, first evaluate 3 · 5, getting 15, then add that to 6, getting 21. Multiplying by 2 completes our evaluation of this expression: 2 6 + 3 (1 + 4) = 42. 5 21 The Distributive Property The distributive property connects addition and multiplication, converting a product with a sum into a sum of two products.
Example 3 Expand (a + b)(c + d). solution Think of (c + d) as a single number and then apply the distributive property to the expression above, getting (a + b)(c + d) = a(c + d) + b(c + d). Now apply the distributive property twice more, getting (a + b)(c + d) = ac + ad + bc + bd. If you are comfortable with the distributive property, there is no need to memorize the last formula from the example above, because you can always derive it again. Furthermore, by understanding how the identity above was obtained, you should have no trouble finding formulas for more complicated expressions such as (a + b)(c + d + t).
