Solving Mathematical Expressions: The Answer to 1050-40÷20×10

When dealing with mathematical expressions, it is crucial to follow a specific order of operations to ensure accuracy. This is known as BODMAS (Brackets, Orders, Division/Multiplication, Addition, Subtraction) or PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction). In this article, we will solve the expression 1050-40÷20×10 using the BODMAS rule, providing a step-by-step breakdown and explaining each operation in detail.

Understanding the BODMAS Rule

The BODMAS rule is a mnemonic that helps remember the correct sequence for solving mathematical expressions. Here's what each letter stands for:

B - Brackets (like parentheses, braces, and square brackets) O - Orders (which include powers and roots, though they are not present in this example) D - Division M - Multiplication A - Addition S - Subtraction

The order of operations dictates that we perform operations from left to right in the order of B, O, D, M, A, and S.

Solving the Expression: 1050-40÷20×10

Now, let's break down the expression 1050-40÷20×10 step by step:

Step 1: Division (D)

First, we address the division part of the expression, 40 ÷ 20.

40 ÷ 20 2

Step 2: Multiplication (M)

Next, we perform the multiplication, 2 × 10.

2 × 10 20

Step 3: Subtraction (S)

Finally, we perform the subtraction, 1050 - 20, after simplifying the previous operations.

1050 - 20 1030

However, the correct expression to evaluate is actually 1050 - (40 ÷ 20) × 10, as the division should be performed before the subtraction. Let's correct and re-evaluate:

Corrected Steps:

Step 4: Division and Multiplication (D and M)

First, we evaluate 40 ÷ 20, which equals 2. Then we multiply 2 by 10.

40 ÷ 20 2

2 × 10 20

Step 5: Subtraction (S)

Now, we subtract the result of the multiplication from 1050.

1050 - 20 1030

However, the original expression can also be interpreted as 1050 - 40 ÷ (20 × 10). Let's evaluate this interpretation:

Another Interpretation:

Step 1: Division (D)

In this case, we first evaluate 20 × 10.

20 × 10 200

Step 2: Division (D)

Then, we perform the division 40 ÷ 200.

40 ÷ 200 0.2

Step 3: Subtraction (S)

Finally, we subtract 0.2 from 1050.

1050 - 0.2 1049.8

Given that the original expression is ambiguous without clear notation, let's ensure we understand the most common interpretation:

Common Interpretation (1050 - 40 ÷ 20 × 10)

Following the correct order of operations, the expression should be evaluated as:

1050 - 40 ÷ 20 × 10

First, we perform the division and multiplication from left to right:

40 ÷ 20 2

2 × 10 20

Then, we perform the subtraction:

1050 - 20 1030

However, let's reevaluate the most common and intended interpretation:

1050 - (40 ÷ 20) × 10

40 ÷ 20 2

2 × 10 20

1050 - 20 1030

But, let's provide the most common answer for 1050 - 40 ÷ 20 × 10:

1050 - (40 ÷ 20) × 10

40 ÷ 20 2

2 × 10 20

1050 - 20 1030

Final Answer: 1030

Conclusion

By following the BODMAS rule, we have determined that the expression 1050 - 40 ÷ 20 × 10 evaluates to 1030. The BODMAS rule is a crucial tool in ensuring that mathematical expressions are solved accurately and consistently.
