Problem 2 - Elementary Algebra

Question

Use the grouping symbols to help perform the following operations. $$3(1+8)$$

Step-by-Step Solution

Answer

Answer: 27

Step 1: Perform addition inside the parentheses

The expression is $$3(1+8)$$. Start by calculating the sum inside the parentheses: $$(1+8)=9$$

Step 2: Multiply by the number outside the parentheses

Now that we have found the sum inside the parentheses, we can multiply it by the number outside: $$3(9)$$ Multiply 3 by 9: $$3 \times 9 = 27$$ The result of the expression $$3(1+8)$$ is 27.
