Subtraction: what is basic subtraction
Basic subtraction is an arithmetic operation that involves finding the difference between two or more numbers. It is one of the four fundamental operations in mathematics, along with addition, multiplication, and division.
To perform basic subtraction, you start by aligning the numbers to be subtracted vertically. Then, you subtract the digits in each column, working from right to left. If the digit on top is greater than the digit below it, you can subtract without borrowing. However, if the digit on top is less than the digit below it, you need to borrow by subtracting 10 from the digit to its left and adding 10 to the digit being subtracted.
For example, let’s say we want to subtract 7 from 15. We would align the numbers vertically and subtract the digits in each column:

“`
15
– 7
——-
“`

The digit in the ones place is 5, which is greater than 7, so we can subtract directly:

“`
15
– 7
——-
8
“`

Therefore, 15 minus 7 equals 8.

What Is a Subtraction Table in Math?
A subtraction table in math is a tabular representation of numbers arranged in rows and columns that enables us to determine the difference between two numbers only via observation rather than through calculation.

Subtraction is one of the four basic arithmetic operations in mathematics. Subtraction in math is a process of finding the difference between two numbers. Let’s quickly understand important terms in a subtraction equation.
- Minuend: The first number, the number from which another number will be subtracted
- Subtrahend: The second number, the number to be subtracted
Identifying the subtrahend and the minuend will help in reading and writing the subtraction table.

The subtraction table makes the process of subtraction easier. It is formed by arranging the numbers in rows and columns in a certain pattern.

$Minuend, subtrahend in subtraction$

Using the subtraction table, we can calculate the difference between two numbers without doing the calculation.

A basic subtraction chart takes you through the subtraction of numbers from 1 to 10.

Let’s take an example to understand how to read a subtraction table:

Ex: 6 – 9

Step 1: Look first for a number in the horizontal row. (Here, we need to find number 6 in the horizontal row)

Step 2: subtract from that number by selecting a number in the leftmost column (Here, we need to find number 9 in the FIRST column)

Step 3: Move along the row and down the column to find the cell where they meet. The number written in the cell is the answer. The answer here is -3.
