Understanding the Problem
In this article, we will tackle a simple mathematical problem that involves subtraction. We want to calculate 36 decreased by 20. This can be represented mathematically as 36 - 20. We will break down the solution into three easy steps.
Step 1: Understand the Subtraction Operation
Before we dive into the solution, it’s essential to understand the concept of subtraction. Subtraction is an arithmetic operation that represents the difference between two numbers. In this case, we want to find the difference between 36 and 20.
🤔 Note: Subtraction is denoted by the minus sign (-).
Step 2: Perform the Subtraction Operation
Now, let’s perform the subtraction operation:
36 - 20 =?
To do this, we can use a number line or simply count back 20 from 36.
Counting back 20 from 36:
36, 35, 34, 33, 32, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16
As we can see, counting back 20 from 36 brings us to 16.
Step 3: Write the Final Answer
Therefore, 36 decreased by 20 is equal to 16.
📝 Note: The answer can be represented mathematically as 36 - 20 = 16.
The solution to this problem is straightforward and involves a simple subtraction operation. By following these three easy steps, you can calculate 36 decreased by 20.
To summarize, the key points are:
- Understand the subtraction operation and its representation (denoted by the minus sign (-)).
- Perform the subtraction operation by counting back 20 from 36.
- Write the final answer, which is 16.
By following these steps, you can easily calculate 36 decreased by 20.
