Solving $150 - $96.50: A Step-by-Step Guide

Let's tackle this subtraction problem together! Subtracting money, like figuring out $150 - $96.50, is something we often encounter in daily life, whether we're calculating change, balancing a budget, or just trying to understand our spending. It's a fundamental skill, and I'm here to guide you through it step by step, making sure it's clear and easy to understand. No complicated jargon, just plain and simple math! I will break down the process into manageable parts, ensuring you grasp each concept before moving on to the next. This way, you’ll not only solve this particular problem but also gain the confidence to handle similar calculations on your own. So, grab a pen and paper, and let's get started!

Understanding the Basics

Before we dive into the nitty-gritty, let's ensure we're all on the same page regarding the basics. When we're dealing with money, we're essentially working with decimal numbers. The dollar amount is the whole number, and the cents are the decimal part. In our problem, $150 is a whole number, which can also be written as $150.00 to align it with $96.50, which has cents. Understanding this alignment is crucial because it helps us keep our place values correct during subtraction. Remember those place values from school? Ones, tens, hundreds, tenths, hundredths? They're super important here! We'll be lining up these place values to ensure we subtract the correct amounts from each other.

Why is this important? Imagine trying to subtract 50 cents from $150 without recognizing that 50 cents is $0.50. You might end up with a wildly incorrect answer. So, recognizing the structure of decimal numbers in the context of money is the first key step to solving this problem accurately. We are setting the stage for a smooth and error-free calculation by ensuring we understand this basic principle. Think of it like building a house; a strong foundation is essential for a stable structure. In this case, understanding decimal alignment is our strong foundation.

Step-by-Step Subtraction

Okay, guys, let's get into the real deal! Here's how to subtract $96.50 from $150 step-by-step:

Write down the numbers, aligning the decimal points:
```
$150.00
- $96.50
-------
```
Lining up the decimal points is super important. It ensures that you're subtracting cents from cents and dollars from dollars. Think of it like organizing your closet – you wouldn't put your shoes with your shirts, would you? Same principle here!
Start subtracting from the rightmost column (the hundredths place):

We have 0 - 0, which equals 0. So, write down 0 in the hundredths place.
```
$150.00
- $96.50
-------
     0
```
Move to the next column (the tenths place):

We need to subtract 5 from 0. But wait, we can't do that without borrowing! So, we borrow 1 from the ones place. The 0 in the ones place becomes 10, and we lend 1 to the tenths place, making it 10 as well. Now we have 10 - 5, which equals 5. Write down 5 in the tenths place.
```
$149.10  <-- Borrowing happened here!
- $96.50
-------
   .50
```
Borrowing can be tricky, but it's just about regrouping. Think of it like exchanging a ten-dollar bill for ten one-dollar bills when you need smaller denominations.
Move to the ones place:

Remember, we borrowed 1 from the ones place, so now we have 9 - 6, which equals 3. Write down 3 in the ones place.
```
$149.10
- $96.50
-------
  3.50
```
Move to the tens place:

We have 4 - 9. Again, we can't do that without borrowing. So, we borrow 1 from the hundreds place. The 1 in the hundreds place becomes 0, and we lend 1 to the tens place, making it 14. Now we have 14 - 9, which equals 5. Write down 5 in the tens place.
```
$149.10  <-- Borrowing happened here!
- $96.50
-------
 53.50
```
Finally, move to the hundreds place:

We have 0 in the hundreds place since we borrowed from it. So, we write down 0. (No need to write it, actually!)
Put it all together:
```
$150.00
- $96.50
-------
$ 53.50
```
So, $150 - $96.50 = $53.50. Ta-da! You did it!

Double-Checking Your Work

Alright, before you go celebrating, let's make sure we got the right answer. There are a couple of ways to double-check our work.

Method 1: Addition

The easiest way to check subtraction is by doing addition. Simply add the result ($53.50) to the amount you subtracted ($96.50) and see if it equals the original amount ($150). Let's do it:

$53.50
+ $96.50
-------
$150.00

Woo-hoo! It matches! This confirms that our subtraction was correct.

Method 2: Estimation

Another way to quickly check is to estimate. Round $96.50 to the nearest ten, which is $100. Then subtract $100 from $150, which gives you $50. Since we rounded $96.50 up, our estimate of $50 should be a bit lower than the actual answer. Our calculated answer is $53.50, which is indeed a bit higher than $50, so it seems reasonable.
