Subtract and Check: A Step-by-Step Guide to Solving Mathematical Operations

In mathematics, subtraction is a fundamental operation that involves finding the difference between two numbers. It is an essential skill that is used in various mathematical operations, including algebra, geometry, and calculus. In this article, we will focus on subtracting two decimal numbers and checking the result.

The problem we are given is to subtract 79.39 from 774.5. This is a simple subtraction problem that requires us to follow the standard rules of subtraction.

Step 1: Line Up the Numbers

To start solving the problem, we need to line up the numbers correctly. The first number, 774.5, is the minuend, and the second number, 79.39, is the subtrahend. We need to line up the decimal points and the digits in the correct positions.

Step 2: Subtract the Numbers

Now that we have lined up the numbers, we can start subtracting. We will start by subtracting the digits in the ones place. Since 4 is less than 9, we will need to borrow from the tens place.

Borrowing from the Tens Place

To borrow from the tens place, we will subtract 1 from the tens digit and add 10 to the ones digit. This will give us a new ones digit of 14.

Subtracting the Ones Digit

Now that we have borrowed from the tens place, we can subtract the ones digit. We will subtract 9 from 14, which gives us 5.

Subtracting the Tens Digit

Next, we will subtract the tens digit. We will subtract 7 from 7, which gives us 0.

Subtracting the Hundreds Digit

Finally, we will subtract the hundreds digit. We will subtract 7 from 7, which gives us 0.

The Result

Now that we have subtracted all the digits, we can write the result. The result of subtracting 79.39 from 774.5 is 695.11.

Checking the Result

To check the result, we can add the subtrahend to the result. If the result is correct, the sum should be equal to the minuend.

Adding the Subtrahend to the Result

To add the subtrahend to the result, we will add 79.39 to 695.11. This gives us a sum of 774.5.

In conclusion, subtracting 79.39 from 774.5 gives us a result of 695.11. We can check the result by adding the subtrahend to the result, and if the sum is equal to the minuend, we can be confident that the result is correct.

The final answer is: 695.11

This problem is a simple example of subtraction with decimal numbers. It requires us to follow the standard rules of subtraction and to check the result by adding the subtrahend to the result. This problem is an essential skill that is used in various mathematical operations, including algebra, geometry, and calculus.

Frequently Asked Questions: Subtraction with Decimal Numbers

In our previous article, we discussed how to subtract decimal numbers and check the result. In this article, we will answer some frequently asked questions related to subtraction with decimal numbers.

Q: What is the difference between subtracting decimal numbers and whole numbers?

A: The main difference between subtracting decimal numbers and whole numbers is that decimal numbers have a decimal point, which can affect the subtraction process. When subtracting decimal numbers, we need to line up the decimal points and subtract the digits in the correct positions.

Q: How do I handle the decimal point when subtracting decimal numbers?

A: When subtracting decimal numbers, we need to line up the decimal points and subtract the digits in the correct positions. If the digits in the ones place are different, we need to borrow from the tens place or higher places. If the digits in the ones place are the same, we need to subtract the digits in the tens place or higher places.

Q: What if I get a negative result when subtracting decimal numbers?

A: If you get a negative result when subtracting decimal numbers, it means that the subtrahend is greater than the minuend. In this case, you can change the sign of the result to make it positive.

Q: How do I check the result of subtracting decimal numbers?

A: To check the result of subtracting decimal numbers, you can add the subtrahend to the result. If the sum is equal to the minuend, you can be confident that the result is correct.

Q: What if I make a mistake when subtracting decimal numbers?

A: If you make a mistake when subtracting decimal numbers, you can try to identify the error and correct it. You can also use a calculator or a computer program to check your result.

Q: Can I use a calculator to subtract decimal numbers?

A: Yes, you can use a calculator to subtract decimal numbers. However, it's always a good idea to check your result by adding the subtrahend to the result.

Q: How do I round decimal numbers when subtracting?

A: When subtracting decimal numbers, you can round the result to the nearest hundredth or thousandth, depending on the problem.

Q: Can I subtract decimal numbers with different numbers of decimal places?

A: Yes, you can subtract decimal numbers with different numbers of decimal places. However, you need to line up the decimal points and subtract the digits in the correct positions.

Q: How do I handle decimal numbers with zeros after the decimal point?

A: When subtracting decimal numbers with zeros after the decimal point, you can ignore the zeros and subtract the digits in the correct positions.

In conclusion, subtracting decimal numbers requires attention to detail and a clear understanding of the subtraction process. By following the steps outlined in this article, you can confidently subtract decimal numbers and check the result.
