Short Answer

Expert verified

The value of the expression $18 \div 9 + 2 \cdot 6$ is 14.

Step by step solution

Step 1. Order of operations.

In order to evaluate an expression, the order of operations must be followed, which is:

Evaluate the expressions inside the bracket
Evaluate the powers
Multiply and/or divide
Add and/ or subtract

The evaluation takes place from left to right.

Step 2. Divide 18 by 9.

As per the order of operations, first, divide 18 by 9.

$18 \div 9 + 2 \cdot 6 = 2 + 2 \cdot 6$

Step 3. Multiply from left to right.

To further evaluate multiply 2 by 6.

$\begin{array}{l} 18 \div 9 + 2 \cdot 6 = 2 + 2 \cdot 6 \\ = 2 + 12 \end{array}$

Step 4. Apply addition operation.

Add 2 and 12.

$\begin{array}{l} 18 \div 9 + 2 \cdot 6 = 2 + 2 \cdot 6 \\ = 2 + 12 \\ = 14 \end{array}$

Therefore, the expression is equal to 14.
