Complete The Tables: Addition And Subtraction Practice

Hey guys! Let's dive into some fun with numbers today! We're going to be working on completing some tables involving addition and subtraction. This is a fantastic way to sharpen our math skills and get comfortable working with different numbers. So, grab your pencils, and let's get started!

Addition Table Fun

Let's kick things off with an addition table. These tables might look a little intimidating at first, but they're super easy to understand. Basically, we're going to add the number in the first column to each of the numbers in the first row. The result of each addition will go in the corresponding cell. Think of it like a grid where you're finding the sum at the intersection of a row and a column. We'll be focusing on addition problems in this section. Mastering addition is crucial because it's a foundational skill in mathematics. It helps us understand how numbers combine and grow, and it's used in countless real-life situations, from calculating grocery bills to planning budgets. When you practice addition, you're not just memorizing facts; you're building your number sense. You'll start to see patterns, understand relationships between numbers, and develop strategies for solving problems quickly and efficiently. The more you practice, the more confident and fluent you'll become in your addition skills. This confidence will carry over into other areas of math, making more complex concepts easier to grasp. Remember, addition is like building blocks. Each concept you master adds to your foundation, making it stronger and more reliable. So, take your time, work through the problems carefully, and enjoy the process of learning and growing!

Here’s the table we'll be working with:

Okay, so we need to add 976 to each number in the top row. Let's break it down step by step.

• 1 618 + 976: To solve this, we can add the numbers column by column, starting from the right. 8 + 6 is 14, so we write down 4 and carry over 1. Then, 1 + 7 + 1 (carried over) is 9. Next, 6 + 9 is 15, so we write down 5 and carry over 1. Finally, 1 + 1 (carried over) is 2. So, 1 618 + 976 = 2 594.
• 2 901 + 976: Again, let's go column by column. 1 + 6 is 7. 0 + 7 is 7. 9 + 9 is 18, so write down 8 and carry over 1. 2 + 1 (carried over) is 3. So, 2 901 + 976 = 3 877.
• 3 546 + 976: 6 + 6 is 12, write down 2 and carry over 1. 4 + 7 + 1 (carried over) is 12, write down 2 and carry over 1. 5 + 9 + 1 (carried over) is 15, write down 5 and carry over 1. 3 + 1 (carried over) is 4. So, 3 546 + 976 = 4 522.
• 3 745 + 976: 5 + 6 is 11, write down 1 and carry over 1. 4 + 7 + 1 (carried over) is 12, write down 2 and carry over 1. 7 + 9 + 1 (carried over) is 17, write down 7 and carry over 1. 3 + 1 (carried over) is 4. So, 3 745 + 976 = 4 721.

Now, let's fill in our table:

Awesome! We've completed our first addition table. See? It wasn't so bad after all!

Subtraction Table Challenge

Next up, we've got a subtraction table. This one is similar to the addition table, but instead of adding, we'll be subtracting the number in the first column from each of the numbers in the first row. Subtraction is just the reverse of addition. It helps us understand how much is left when we take something away. It's essential for managing our finances, measuring ingredients in recipes, and solving all sorts of daily problems. When you practice subtraction, you're honing your ability to find differences between numbers. You'll learn to identify patterns and relationships that make calculations easier. You'll also develop important problem-solving skills, like how to regroup numbers or break down complex problems into smaller steps. Like addition, subtraction builds a foundation for more advanced math concepts. It's crucial for understanding algebra, geometry, and even calculus. The better you are at subtraction, the more confident you'll feel tackling these more challenging subjects. So, take your time, work through each problem carefully, and don't be afraid to ask for help if you get stuck. Remember, the goal is to learn and grow, and every problem you solve brings you one step closer to mastering subtraction! Let's tackle this next table together and become subtraction superstars!

Here's our subtraction table:

Alright, let's subtract 748 from each number in the top row.

• 1 400 - 748: We'll subtract column by column, again starting from the right. 0 - 8 isn't possible without borrowing, so we need to borrow from the tens place. But the tens place is also 0, so we need to borrow from the hundreds place. We borrow 1 from the 4 (making it 3), which gives us 10 in the hundreds place. We then borrow 1 from the hundreds place (making it 9), giving us 10 in the tens place. Finally, we borrow 1 from the tens place (making it 9), giving us 10 in the ones place. Now we have 10 - 8 = 2. In the tens place, 9 - 4 = 5. In the hundreds place, 3 - 7 isn't possible, so we borrow 1 from the thousands place (making it 0), giving us 13 in the hundreds place. 13 - 7 = 6. So, 1 400 - 748 = 652.
• 2 236 - 748: 6 - 8 requires borrowing. We borrow 1 from the 3 (making it 2), giving us 16 - 8 = 8. Now, 2 - 4 also requires borrowing. We borrow 1 from the 2 in the hundreds place (making it 1), giving us 12 - 4 = 8. 1 - 7 requires borrowing again. We borrow 1 from the 2 in the thousands place (making it 1), giving us 11 - 7 = 4. Finally, we have 1 left in the thousands place. So, 2 236 - 748 = 1 488.
• 3 002 - 748: 2 - 8 requires borrowing. We need to borrow across the zeros. We borrow 1 from the 3 (making it 2), giving us 10 in the hundreds place. We borrow 1 from the hundreds place (making it 9), giving us 10 in the tens place. Then, we borrow 1 from the tens place (making it 9), giving us 12 in the ones place. 12 - 8 = 4. 9 - 4 = 5. 9 - 7 = 2. And finally, we have 2 left in the thousands place. So, 3 002 - 748 = 2 254.
• 4 015 - 748: 5 - 8 requires borrowing. We borrow 1 from the 1 (making it 0), giving us 15 - 8 = 7. Now, 0 - 4 requires borrowing. We need to borrow across the zero in the hundreds place. We borrow 1 from the 4 (making it 3), giving us 10 in the hundreds place. We borrow 1 from the hundreds place (making it 9), giving us 10 in the tens place. So, 10 - 4 = 6. 9 - 7 = 2. And finally, we have 3 left in the thousands place. So, 4 015 - 748 = 3 267.

Let's fill in the subtraction table with our results:

Woohoo! We did it! We successfully completed the subtraction table. Give yourselves a pat on the back!
