Understanding the Expression: 32.32 65-4-4.44 4.21
Before we dive into solving the problem, let’s break down the expression and understand what each part means.
- 32.32 and 65: These numbers will be multiplied together.
- The minus sign (-): This means we will subtract something from our result.
- 4.44 and 4.21: These numbers will also be multiplied together.
- Another minus sign (-): This tells us that we will subtract the result of 4.44⋅4.214.44 \cdot 4.214.44⋅4.21 from the first part of the expression.
To solve this expression correctly, we need to use something called the Order of Operations. This tells us which steps to follow first, so we get the right answer.
Order of Operations (PEMDAS/BODMAS)
PEMDAS stands for:
- Parentheses
- Exponents
- Multiplication and Division
- Addition and Subtraction
You may have heard it as BODMAS too:
- Brackets
- Orders (Exponents)
- Division and Multiplication
- Addition and Subtraction
Multiplication comes before subtraction, so we’ll need to multiply first before we subtract.
Step-by-Step Breakdown of 32.32 65-4-4.44 4.21
Now that we understand the components of the expression and the order of operations, let’s solve the problem step by step.
Step 1: Multiply 32.32 by 65
The first thing we need to do is multiply 32.32 by 65. When multiplying large numbers, it’s helpful to line them up carefully or use a calculator to make sure you don’t make any mistakes.
32.32⋅65=2100.8
So the first part of our expression is now 2100.8.
Step 2: Subtract 4 from the Result
Next, we need to subtract 4 from the result of 2100.8.
2100.8−4=2096.8
So far, we have simplified the expression to 2096.8−4.44⋅4.21.
Step 3: Multiply 4.44 by 4.21
Now, we move to the second multiplication part of the expression. Let’s multiply 4.44 by 4.21.
4.44⋅4.21=18.6924
So the second part of our expression is 18.6924.
Step 4: Subtract the Result of 4.44⋅4.21 from 2096.8
Finally, we subtract the result of 4.44⋅4.21 (which is 18.6924) from 2096.8.
2096.8−18.6924=2078.1076
The final answer is 2078.1076.
