Simplify using order of operations.
18 + 4 • 3
A. 66
B. 30
C. 86
D. 122
18+4*3 = 18+12 = 30.
its b
To simplify the expression using the order of operations (also known as PEMDAS), we need to perform the multiplication before the addition.
First, we multiply 4 and 3:
4 • 3 = 12
Now, we can add 18 and 12:
18 + 12 = 30
Therefore, the simplified expression is 30.
So, the correct answer is B. 30.
To simplify the expression using the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction), follow these steps:
Step 1: Perform any calculations within parentheses if there are any. In this case, there are no parentheses.
Step 2: Evaluate any exponents if there are any. There are no exponents in this expression.
Step 3: Perform multiplication and division from left to right. In this case, there is multiplication involved: 4 • 3. Multiply 4 by 3 to get 12.
Step 4: Perform addition and subtraction from left to right. In this case, there's addition involved: 18 + 12. Add 18 and 12 to get 30.
Therefore, the simplified expression is 30.
The correct answer is B. 30.
