What is the value of the expression?
30 - (5 x 4) + 2
12
Yes.
To find the value of the expression 30 - (5 x 4) + 2, you can follow the order of operations, which states that you should perform any calculations inside parentheses first, then multiplication and division from left to right, and finally addition and subtraction from left to right.
First, we will calculate within the parentheses:
5 x 4 = 20
Now we can substitute the result back into the expression:
30 - 20 + 2
Next, perform the subtraction:
30 - 20 = 10
Finally, perform the addition:
10 + 2 = 12
Therefore, the value of the expression 30 - (5 x 4) + 2 is 12.
To find the value of the expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
In the given expression, we have parentheses and multiplication. So, we first need to perform the multiplication inside the parentheses, and then perform the subtraction and addition.
Let's break it down step by step:
Step 1: Multiply 5 by 4:
5 x 4 = 20
The expression becomes:
30 - 20 + 2
Step 2: Perform the subtraction:
30 - 20 = 10
The expression becomes:
10 + 2
Step 3: Perform the addition:
10 + 2 = 12
Therefore, the value of the expression 30 - (5 x 4) + 2 is 12.
