In mathematics, specific terms are used to identify the different numbers involved in subtraction operations. The subtrahend is defined as the number being subtracted from another number. In a standard subtraction equation like 5 - 2 = 3, the number 2 is the subtrahend. Meanwhile, the number from which another is being subtracted (5 in this example) is called the minuend, and the result (3) is called the difference. We can express this relationship as: minuend - subtrahend = difference.

Subtraction follows specific mathematical properties that distinguish it from other operations. Unlike addition, subtraction is not commutative, meaning that changing the order of the numbers will change the result (a - b ≠ b - a). It is also not associative, which means that the grouping of operations matters when subtracting more than two numbers (a - (b - c) ≠ (a - b) - c). These properties make it particularly important to properly identify which number is serving as the subtrahend in any subtraction problem.

Examples of Subtrahend in Mathematical Problems Example 1: Word Problem with Subtraction Problem:

Ms. X collected 50 apples falling from a tree in her neighborhood. At the same time, she also bought some apples from a store on her way back home. Calculate and find out how many apples she bought from the store if she has a total of 62 apples with her now.

Step-by-step solution:

Step 1, Identify what we know and what we're looking for:

Ms. X collected 50 apples from the tree. Ms. X now has a total of 62 apples. We need to find how many apples she bought from the store.

Step 2, Determine the mathematical operation needed:

Since we know the final amount (62) and one source of apples (50), we need to find the difference. This calls for subtraction: Total apples - Apples from tree = Apples from store

Step 3, Perform the subtraction:

62 - 50 = 12 Therefore, Ms. X bought 12 apples from the store. Example 2: Identifying the Subtrahend Problem:

In the equation below, identify which number is the subtrahend.

50 - 8 = 42 Step-by-step solution:

Step 1, Recall the definition of a subtrahend:

The subtrahend is the number being subtracted from another number.

Step 2, Examine the structure of a subtraction equation:

In the format "minuend - subtrahend = difference" Looking at 50 - 8 = 42, we have 50 as the minuend and 8 following the subtraction sign.

Step 3, Therefore, 8 is the subtrahend in this equation.

Example 3: Solving a Word Problem with Subtraction Problem:

A farmer harvested 120 oranges from his orchard. After selling some oranges at the market, he had 85 oranges remaining in his basket. How many oranges did he sell at the market?

Step-by-step solution:

Step 1, Identify what we know and what we're looking for:

Total oranges harvested: 120 Oranges remaining after sale: 85 Goal: Find how many oranges were sold

Step 2, Determine the mathematical operation:

To find the number sold, subtract remaining oranges from total: Operation: Total oranges - Remaining oranges = Oranges sold

Step 3, Set up the equation:

120 - Oranges sold = 85

Step 4, Solve the equation:

Oranges sold = 120 - 85 = 35

Step 5, Conclusion:

The farmer sold 35 oranges at the market. Comments(7)LLawyerGraceNovember 4, 2025I've used this subtrahend def to teach my students. It's clear & the examples helped them grasp the concept quickly. Thanks!
