Introduction

When we encounter mathematical expressions, it's essential to understand the notation and the operations involved. In this case, we have an expression that appears to represent a long division problem. However, upon closer inspection, it becomes clear that the notation is incorrect. In this article, we'll delve into the correct representation of the long division problem and explore the steps involved in solving it.

Understanding the Notation

The given expression seems to represent a long division problem, where 72 is being divided by 3. However, the notation is incorrect, and it's essential to understand the correct representation of this problem. Long division is a mathematical operation that involves dividing a dividend (the number being divided) by a divisor (the number by which we are dividing) to find the quotient (result) and the remainder.

Correct Representation of the Long Division Problem

A more appropriate representation of the long division problem would be:

Perform the long division of 72 by 3

This notation clearly indicates that we are dividing 72 by 3, and the result will be the quotient and the remainder.

Steps Involved in Solving the Long Division Problem

To solve the long division problem, we need to follow these steps:

Step 1: Divide the Dividend by the Divisor

The first step in solving the long division problem is to divide the dividend (72) by the divisor (3). This will give us the quotient.

Step 2: Multiply the Quotient by the Divisor

Once we have the quotient, we need to multiply it by the divisor (3) to get the product.

Step 3: Subtract the Product from the Dividend

Next, we need to subtract the product from the dividend (72) to get the remainder.

Step 4: Bring Down the Next Digit

If the remainder is not zero, we need to bring down the next digit from the dividend and repeat the process.

Step 5: Repeat the Process Until the Remainder is Zero

We need to repeat the process until the remainder is zero. This will give us the final quotient and remainder.

Solving the Long Division Problem

Now that we have the correct representation of the long division problem, let's solve it step by step.

Step 1: Divide the Dividend by the Divisor

To divide 72 by 3, we get a quotient of 24.

Step 2: Multiply the Quotient by the Divisor

Next, we multiply the quotient (24) by the divisor (3) to get the product, which is 72.

Step 3: Subtract the Product from the Dividend

Since the product (72) is equal to the dividend (72), the remainder is zero.

Step 4: Bring Down the Next Digit

Since the remainder is zero, we don't need to bring down the next digit.

Step 5: Repeat the Process Until the Remainder is Zero

Since the remainder is zero, we have reached the end of the long division process.

Conclusion

In conclusion, the expression seemingly representing a long division problem was actually a representation of the long division of 72 by 3. By following the correct steps involved in solving the long division problem, we were able to find the quotient and remainder. This exercise highlights the importance of understanding the notation and the operations involved in mathematical expressions.

Q&A: Long Division

Q: What is long division?

A: Long division is a mathematical operation that involves dividing a dividend by a divisor to find the quotient and the remainder.

Q: What is the dividend in long division?

A: The dividend is the number being divided, also known as the numerator.

Q: What is the divisor in long division?

A: The divisor is the number by which we are dividing, also known as the denominator.

Q: What is the quotient in long division?

A: The quotient is the result of the division, which is the number of times the divisor fits into the dividend.

Q: What is the remainder in long division?

A: The remainder is the amount left over after the division, which is the amount that the divisor does not fit into the dividend.

Q: How do I perform long division?

A: To perform long division, follow these steps:

Divide the dividend by the divisor
