Complete the Tables: Addition and Subtraction Practice

Hey guys! Today, we're diving into some fun math exercises focused on addition and subtraction. We've got some tables here that need filling, and it's a great way to sharpen those arithmetic skills. So, let's jump right in and complete these tables together! It’s super important to practice these skills, because they are the foundation for more advanced math. Think of it like building blocks – you need a strong base to build something amazing!

Part A: Addition and Subtraction Table

Let's kick things off with our first table, where we'll be adding and subtracting different numbers. This will help us see how these operations work side-by-side and how they relate to each other. Remember, addition is combining quantities, while subtraction is finding the difference. This exercise will not only improve your calculation speed but also enhance your understanding of numerical relationships.

| a    | b    | a + b  | a - b  |
| ---- | ---- | ----- | ----- |
| 1425 | 314  |       |       |
| 2567 | 2321 |       |       |
| 3645 | 3241 |       |       |
| 7639 | 320  |       |       |

Filling in the First Row (1425 and 314)

Okay, for the first row, we have a = 1425 and b = 314. First, let's tackle the addition part, which is a + b. This means we need to add 1425 and 314. You can do this mentally, on paper, or use a calculator if you need to. Think about aligning the numbers properly and carrying over when necessary. Addition is like making friends with numbers and seeing what they create together! Let’s break it down:

  • 1425 + 314 = 1739

So, in the a + b column, we'll write 1739. Now, let's move on to the subtraction part, which is a - b. This means we need to subtract 314 from 1425. Subtraction is like taking away a part of the group to see what’s left. Again, make sure to align the numbers correctly and borrow if you need to. It’s a fundamental skill that comes in handy in everyday situations, like figuring out how much change you'll get at the store.

  • 1425 - 314 = 1111

So, in the a - b column, we'll write 1111. Great job! We've completed the first row.

Filling in the Second Row (2567 and 2321)

Next up, we have a = 2567 and b = 2321. Let's start with addition again. We need to calculate 2567 + 2321. Remember, practice makes perfect, and the more you do these, the faster and more accurate you'll become. Adding larger numbers can seem intimidating, but if you break it down place by place, it becomes much more manageable.

  • 2567 + 2321 = 4888

We'll put 4888 in the a + b column. Now, let's subtract. We need to find 2567 - 2321. Subtraction helps us understand differences and comparisons, which is crucial in many real-world scenarios. This is an essential skill to master.

  • 2567 - 2321 = 246

So, we write 246 in the a - b column. Awesome! We’re halfway through the table already.

Filling in the Third Row (3645 and 3241)

For the third row, we have a = 3645 and b = 3241. As always, let's start with addition: 3645 + 3241. By now, you should be getting the hang of it! Keep focusing and make sure you are adding each place value accurately. This part is all about precision and attention to detail.

  • 3645 + 3241 = 6886

Write 6886 in the a + b column. Now for subtraction: 3645 - 3241. Keep those subtraction skills sharp. Subtraction is used in countless situations, from managing finances to measuring ingredients while cooking. It’s a superpower for problem-solving!

  • 3645 - 3241 = 404

We write 404 in the a - b column. Fantastic! Only one row left to go.

Filling in the Fourth Row (7639 and 320)

Last but not least, we have a = 7639 and b = 320. Let's add them up: 7639 + 320. This is a great chance to really show off what you've learned. It's rewarding to see how far you’ve come just by completing these few rows. Keep up the fantastic work!

  • 7639 + 320 = 7959

So, 7959 goes in the a + b column. Finally, let's subtract: 7639 - 320. You’re doing great! Each calculation is another step toward mastering these essential math skills. This will give you confidence in your numerical abilities.

  • 7639 - 320 = 7319

And we write 7319 in the a - b column. Woohoo! We've completed the entire table.

Here’s the filled table:

| a    | b    | a + b  | a - b  |
| ---- | ---- | ----- | ----- |
| 1425 | 314  | 1739  | 1111  |
| 2567 | 2321 | 4888  | 246   |
| 3645 | 3241 | 6886  | 404   |
| 7639 | 320  | 7959  | 7319  |

Part B: Completing the Term Table

Now, let's move on to the second table. This one looks a little different, but it’s still about addition. We have a “Term” column and then several other columns with numbers. We need to figure out what operation connects them. This is a fantastic exercise for developing your pattern recognition and logical thinking skills.

| Term   |       |       |       |       |
| ------ | ----- | ----- | ----- | ----- |
| Term   | 2241  | 3124  | 2314  | 4634  |

Understanding the Pattern

Okay, guys, let's analyze this table. It seems like we need to add each of the numbers in the top row to the "Term" in the first column. But we need to figure out what that term actually is. Let’s think step by step. What could be the missing numbers? It's like being a math detective and solving a mystery!

Let's assume that the first
