Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Subtracting Numbers

Subtraction is one of the basic operations in arithmetic. It may sound simple, but it is essential to understand it well as it forms the foundation for more complex mathematics.
When we subtract, we take one number away from another. Think of it as if you have 75 apples and you give away 28. You need to find out how many apples you have left.
In our problem, we are subtracting 28 from 75. The equation is written as: 75 - 28.
Here, 75 is called the 'minuend', and 28 is the 'subtrahend'. The result is known as the 'difference'.
Remember, subtracting a larger number from a smaller number generally results in a negative difference.

Simplifying Expressions

Before you perform subtraction, it is crucial to simplify the expression if needed. In our case, the expression is already straightforward: 75 - 28.
Simplifying expressions can mean breaking down complex equations into simpler parts or re-arranging them to make the calculation easier.
For the given exercise, there's no need to simplify further since 75 and 28 are simple whole numbers. We can directly proceed to subtraction.

Step-by-Step Solutions

Using a step-by-step approach helps ensure that you understand and correctly perform each part of the problem. Here鈥檚 how you can break it down:

Step 1: Understand the Problem: The problem requires us to subtract 28 from 75.
Step 2: Set Up the Equation: Write it down as: 75 - 28. This helps visualize what you're about to do.
Step 3: Perform the Subtraction: Calculate it: 75 - 28. You can do the subtraction mentally, or use a pencil and paper.

Perform it step-by-step:
1. Line up the numbers by their place values.
2. Subtract the ones place: 5 - 8 (Since 5 is less than 8, you need to borrow from the tens place.)
3. After borrowing, subtract 15 - 8 = 7.
4. Move to the tens place: 6 (because you've borrowed 1) - 2 = 4.
Therefore, 75 - 28 = 47.

This method not only simplifies learning but also strengthens your number skills.
