Mathematics often involves various calculations, some of which can be as simple as subtraction. One common example is the expression **300 - 15**. In this article, we will delve into the significance of this calculation, breaking down its components and exploring real-world applications.

## The Calculation

The expression **300 - 15** is a straightforward subtraction problem. Here’s the breakdown:

**300**is the minuend, which is the number from which another number (the subtrahend) is to be subtracted.**15**is the subtrahend, which is the number to be subtracted from the minuend.

### Performing the Calculation

To calculate **300 - 15**, we simply subtract 15 from 300:

```
300
- 15
-----
285
```

Thus, the result of **300 - 15** is **285**.

## Practical Example

This calculation can be applied in various real-life scenarios. For instance, let’s consider a budgeting example:

Imagine you have a budget of **$300** for a shopping spree. If you spend **$15** on lunch, how much money do you have left to spend on shopping?

Using the calculation:

**Total Budget - Amount Spent = Remaining Budget**

So, **$300 - $15 = $285**. You would have **$285** remaining for your shopping.
