Evaluate the expression (8/2) + 23 - 5.
To evaluate the expression, we start by performing the division operation.
(8/2) + 23 - 5 = 4 + 23 - 5
Next, we perform the addition operation:
4 + 23 = 27
Lastly, we perform the subtraction operation:
27 - 5 = 22
Therefore, the evaluation of the expression (8/2) + 23 - 5 is equal to 22.
To evaluate the expression (8/2) + 23 - 5, follow the order of operations, which is also known as PEMDAS (parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right).
Step 1: Begin with parentheses, but in this case, there are no parentheses in the expression.
Step 2: Next, do any exponentiation, but there are no exponents in the expression.
Step 3: Move on to multiplication and division from left to right. We have one division operation, (8/2).
8 divided by 2 equals 4.
So, the expression becomes 4 + 23 - 5.
Step 4: Finally, perform addition and subtraction from left to right.
4 + 23 equals 27.
27 - 5 equals 22.
Therefore, the expression (8/2) + 23 - 5 equals 22.
To evaluate the given expression (8/2) + 23 - 5, we need to follow the order of operations, which is often remembered by the acronym PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Here's how we can evaluate the expression step by step:
1. Start with the expression inside the parentheses. In this case, there are no parentheses, so we move on to the next step.
2. Perform any multiplication or division from left to right. In this expression, we have 8 divided by 2, which equals 4. So, we rewrite the expression as 4 + 23 - 5.
3. Finally, perform any addition or subtraction from left to right. In this expression, we have 4 + 23 - 5. Adding 4 to 23 gives us 27, and subtracting 5 from 27 results in 22.
Therefore, the evaluation of the expression (8/2) + 23 - 5 is equal to 22.
To simplify the expression further, you can also calculate the value of 8/2 first, which is 4, and substitute it into the expression to obtain 4 + 23 - 5. This would still lead to the final answer of 22.
