use pemdas
[20+(16-8)*2]÷9
To solve the expression using PEMDAS (which stands for Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right), we follow these steps:
1. Start by solving the expression inside the parentheses: (16-8) = 8.
2. Then, perform the multiplication: 8 * 2 = 16.
3. Afterward, perform the addition: 20 + 16 = 36.
4. Finally, divide the result by 9: 36 ÷ 9 = 4.
Therefore, the value of the expression [20+(16-8)*2]÷9 using PEMDAS is 4.
To solve the expression using PEMDAS (Order of Operations):
Step 1: Start by simplifying within the parentheses.
16 - 8 = 8
Step 2: Continue within the parentheses by performing the multiplication.
8 * 2 = 16
Step 3: Add the result from Step 2 to 20.
20 + 16 = 36
So far, the expression is now [36 ÷ 9].
Step 4: Perform the division.
36 ÷ 9 = 4
Therefore, the value of the expression [20+(16-8)*2]÷9 using PEMDAS is 4.
