To evaluate the expression using the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right), follow these steps:
1. Begin with the expression: 2 × 2 + 9 ÷ 3 - 5
2. According to PEMDAS, we start with any operations within parentheses. However, there are no parentheses in this expression.
3. Next, evaluate any exponents. Again, there are no exponents in this expression.
4. Moving on to multiplication and division from left to right, we have:
2 × 2 = 4
9 ÷ 3 = 3
So now, our expression becomes: 4 + 3 - 5
5. Lastly, we perform addition and subtraction from left to right:
4 + 3 = 7
7 - 5 = 2
Thus, the value of the expression 2 × 2 + 9 ÷ 3 - 5 is 2.
