Subtraction is an important mathematical operation that we use in our everyday lives. Whether it’s calculating expenses, determining change, or solving complex mathematical equations, knowing how to subtract is essential. In this step-by-step guide, we will break down the process of subtraction and answer some common questions along the way.

Question 1: What is subtraction?

Subtraction is an arithmetic operation used to find the difference between two numbers. It represents taking away or removing a quantity from another.

Question 2: What are the basic terms used in subtraction?

In a subtraction equation, the numbers being subtracted are called the minuend and subtrahend, while the result is called the difference.

Question 3: How do you set up a subtraction equation?

To set up a subtraction equation, write the minuend (the number being subtracted from) followed by the minus sign (-), and then write the subtrahend (the number being subtracted).

Question 4: How do you subtract two numbers?

To subtract two numbers, start by aligning the digits vertically with the units’ places lined up. If the digits in the same place value are not equal, subtract the smaller digit from the larger one. Write the result under the line. Repeat this process for each place value until all digits are subtracted.

Question 5: What happens if the digit being subtracted is larger than the digit being subtracted from?

If the digit being subtracted is larger than the digit being subtracted from, we borrow from the next place value to the left. This is known as regrouping or carrying over. We subtract 1 from the digit to the left and add 10 to the digit we are borrowing from. Then, we subtract as usual.

Question 6: What if the subtrahend has more digits than the minuend?

If the subtrahend has more digits than the minuend, we add zeros to the left of the minuend, making both numbers have the same number of digits. This way, we can easily subtract each corresponding digit.

Question 7: Can you give an example of step-by-step subtraction?

Certainly! Let’s subtract 367 from 891.

First, align the numbers vertically with the units’ places lined up:

891
– 367

Start from the right side. Subtract 7 from 1. Since 1 is less than 7, we need to borrow:

891
– 367
4

Now, borrow from the tens place (carryover) and add 10 to 1, which makes it 11. Subtract 7 from 11, which equals 4, and write it above the line:

891
– 367
4 4

Continuing from left to right, subtract 6 from 8. Write the result:

891
– 367
4 44

Finally, subtract 3 from 8:

891
– 367
4 524

The difference between 891 and 367 is 524.

Subtraction is an essential skill that helps us understand numbers and solve various problems. Understanding the step-by-step process of subtraction allows us to perform accurate calculations accurately and efficiently. Remember to align the digits, borrow if necessary, and subtract each corresponding digit. With practice, subtraction becomes second nature, enabling us to handle more complex mathematical operations confidently.
