by SLV Team 47 views

Hey math enthusiasts! Ready to dive into some calculations? Don't worry, it's gonna be fun! We're gonna tackle some addition, subtraction, and a little bit of 'bigger than' action. This guide breaks down each problem step-by-step, making it super easy to follow. So, grab your pencils and let's get started. We'll start with calculating the sum of two numbers, then move on to finding the difference, and finally, we'll bump up a number by a certain amount. It's like a math adventure, and everyone's invited! Let's get our brains warmed up and ready to crunch some numbers. Whether you're a seasoned pro or just starting out, this will be a great way to brush up on your skills and boost your confidence in math.

Adding It Up: Finding the Sum

Let's kick things off with addition. We're going to calculate the sum of 8974 and 7645. Remember, the sum is just the fancy math word for what you get when you add two or more numbers together. It's like combining two groups of things to see how many you have in total. The goal is simple: find the total value.

To find the sum of 8974 and 7645, we'll set up the problem vertically, aligning the numbers by their place values (ones, tens, hundreds, thousands). This makes the addition process much easier to manage and less prone to errors. So, we'll write one number above the other like this:

8974

  • 7645

Now, let's start adding from the rightmost column, which is the ones column.

  • Ones column: 4 + 5 = 9. Write down 9 below the line in the ones column.
  • Tens column: 7 + 4 = 11. Write down 1 in the tens column and carry-over the other 1 to the hundreds column.
  • Hundreds column: 9 + 6 = 15. Add the carried-over 1: 15 + 1 = 16. Write down 6 in the hundreds column and carry-over 1 to the thousands column.
  • Thousands column: 8 + 7 = 15. Add the carried-over 1: 15 + 1 = 16. Write down 16 in the thousands and ten-thousands columns.

So, putting it all together, we have: 8974

  • 7645

16619

Therefore, the sum of 8974 and 7645 is 16619. Pretty straightforward, right? Addition is a fundamental skill in mathematics, and mastering it opens the door to more complex problem-solving. It's used in everyday situations, from calculating the total cost of groceries to managing budgets. Keep practicing, and you'll become a pro in no time! Let's move on to the next part of our math journey: subtraction!

Subtracting the Numbers: Finding the Difference

Alright, let's switch gears and talk about subtraction. We're going to find the difference between 29816 and 16982. Remember, the difference is the result of taking one number away from another. It tells you how much bigger one number is compared to the other. Now, the main concept is to figure out the value remaining after removing a certain amount from a larger value.

To find the difference between 29816 and 16982, we'll set up the problem vertically, just like we did with addition, making sure to align the place values properly. We write the larger number on top and the smaller number below like this:

29816

  • 16982

Now, let's start subtracting from the rightmost column, which is the ones column.

  • Ones column: 6 - 2 = 4. Write down 4 below the line in the ones column.
  • Tens column: 1 - 8. We can't subtract 8 from 1, so we need to borrow 1 from the hundreds column. The 8 in the hundreds column becomes 7, and the 1 in the tens column becomes 11. Now, 11 - 8 = 3. Write down 3 in the tens column.
  • Hundreds column: 7 - 9. We can't subtract 9 from 7, so we need to borrow 1 from the thousands column. The 9 in the thousands column becomes 8, and the 7 in the hundreds column becomes 17. Now, 17 - 9 = 8. Write down 8 in the hundreds column.
  • Thousands column: 8 - 6 = 2. Write down 2 in the thousands column.
  • Ten-thousands column: 2 - 1 = 1. Write down 1 in the ten-thousands column.

So, putting it all together, we have: 29816

  • 16982

12834

Therefore, the difference between 29816 and 16982 is 12834. Subtraction is a crucial skill used in everyday scenarios, such as calculating change, comparing prices, or tracking expenses. Practicing subtraction helps build a strong foundation for more advanced math concepts. Keep up the great work! Ready for the last part? Let's go!

Increasing the Number: Understanding 'More Than'

Okay, time for the final challenge! We're going to find a number that is 317 greater than 10845. This means we need to add 317 to 10845. This concept is fundamental in understanding the relative values of numbers. The goal here is simple: to determine the new number that results from increasing an initial number by a specific value.

To find the number that is 317 greater than 10845, we'll set up an addition problem, again aligning the place values correctly:

10845

  • 317

Now, let's add from right to left.

  • Ones column: 5 + 7 = 12. Write down 2 in the ones column and carry-over 1 to the tens column.
  • Tens column: 4 + 1 = 5. Add the carried-over 1: 5 + 1 = 6. Write down 6 in the tens column.
  • Hundreds column: 8 + 3 = 11. Write down 1 in the hundreds column and carry-over 1 to the thousands column.
  • Thousands column: 0 + 0 = 0. Add the carried-over 1: 0 + 1 = 1. Write down 1 in the thousands column.
  • Ten-thousands column: 1. Write down 1 in the ten-thousands column.

So, we have: 10845

  • 317

11162

Therefore, the number that is 317 greater than 10845 is 11162. Understanding the concept of 'greater than' is essential in various mathematical contexts, from comparing quantities to solving word problems. This helps us to improve our overall number sense and mathematical thinking. You've now successfully completed all three parts of our math adventure! Keep up the excellent work! And remember, practice makes perfect. Keep exploring, keep learning, and keep having fun with math! You're all doing great!
