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.

What is Addition Table?
Addition operation is defined as the summing of two or more quantities.

An addition table is an arrangement of numbers in a tabular format where the same set of numbers are written in the first row and the first column.

The addition table helps us to quickly arrive at the result of the addition of two numbers just by observing the pattern. The arithmetic operation used to create the addition table is addition represented as (+). The numbers that are being added to fill the addition chart are known as addends. To fill a particular row of an addition table, we will follow the logic of adding numbers keeping one of the addends constant and changing the other addend to fill in all the entries of that corresponding row such as 1 + 1 = 2, 1 + 2 = 3, 1 + 3 = 4 and so on. The addition table is also known as the addition chart.

What is Number Decomposition in Math?
Number decomposition is a foundational concept in mathematics that is often introduced in early education.

When we decompose a number, we are breaking it down into smaller, more manageable parts. This might sound simple, but it forms the backbone of many more complex mathematical concepts like multiplication, division, and fraction comprehension. Decomposing numbers helps children develop a more in-depth understanding of how numbers function and interact with each other.

It is a key part of building number sense and improving mental math skills.
