by ADMIN 53 views

Hey guys! Let's dive into some fun math operations. This article will help you practice your addition and subtraction skills. We've got a bunch of problems here, and your mission is to solve each one and pick the right answer from the choices given. So, grab your thinking caps, and let's get started!

Addition Operations

Let's kick things off with some addition problems. Remember, addition is all about combining numbers to find their total. It’s a fundamental skill, and mastering it will help you in so many areas of life, from splitting a bill with friends to figuring out how many cookies you’ll have if you bake two batches! We'll break down each problem step by step, making sure you understand exactly how we arrive at the solution. So, get ready to add some numbers and have some fun!

24 + 32 =

Okay, our first problem is 24 + 32. To solve this, we need to add the numbers in the ones place first, which is 4 + 2. That gives us 6. Then, we move on to the tens place and add 2 + 3, which gives us 5. So, when we combine the tens and ones, we get 56. Make sense, right? It’s like building blocks, stacking the numbers on top of each other to get the final answer.

Let's break it down:

  • Ones place: 4 + 2 = 6
  • Tens place: 2 + 3 = 5
  • Combined: 56

So, the correct answer is 56. This kind of breakdown is super helpful when you're first learning addition. It keeps things organized and makes sure you don't miss any steps. Keep practicing this, and you'll be adding numbers in your head in no time!

16 + 29 =

Next up, we have 16 + 29. This one is a little trickier because when we add the ones place (6 + 9), we get a number greater than 9. But don't worry, we've got this! When 6 and 9 get together, they make 15, right? But we can't just write 15 in the ones place. Instead, we carry the 1 over to the tens column. This is a super important step in addition, and it’s what makes larger numbers manageable.

Let's break it down, step by step, so we’re all on the same page:

  • Ones place: 6 + 9 = 15. We write down the 5 and carry the 1 to the tens place.
  • Tens place: 1 (carried over) + 1 + 2 = 4
  • Combined: 45

So, the correct answer here is 45. See how carrying the one works? It's like giving the tens column a little extra help. This method is essential for adding larger numbers, and once you get the hang of it, you’ll be adding like a pro. Keep practicing, and you’ll see how quickly it becomes second nature!

74 + 13 =

Alright, let's tackle 74 + 13. This one is pretty straightforward, making it a great problem to build our confidence. We start, as always, with the ones place: 4 + 3. That's a solid 7, no carrying needed here! Now, we move to the tens place, where we have 7 + 1. Easy peasy, that’s 8. So, we put the 8 in the tens place and the 7 in the ones place.

Let's break it down, just to be super clear:

  • Ones place: 4 + 3 = 7
  • Tens place: 7 + 1 = 8
  • Combined: 87

So, the correct answer is 87. Sometimes, you’ll come across problems that don't involve carrying, and these are fantastic for reinforcing the basics. They help you get really comfortable with the process, so when you do encounter those trickier problems, you’ll be ready for them!

38 + 47 =

Okay, let's dive into 38 + 47. This one’s another good example of addition where we’ll need to carry a digit, so pay close attention! First up, we add the ones: 8 + 7. What do we get? That's right, 15. Just like before, we write down the 5 in the ones place and carry the 1 over to the tens column. It's like giving the tens a little nudge to remind them we have extra to add.

Here's the step-by-step breakdown:

  • Ones place: 8 + 7 = 15. Write down the 5, carry the 1.
  • Tens place: 1 (carried over) + 3 + 4 = 8
  • Combined: 85

So, the correct answer is 85. Remember, carrying the digit is a crucial part of addition, especially when dealing with larger numbers. It's like having a special tool in your math toolkit. The more you practice with carrying, the easier it will become, and the more confident you’ll feel tackling any addition problem. So, keep at it, and you’ll master this in no time!

Subtraction Operations

Now, let's switch gears and tackle some subtraction problems! Subtraction is all about taking away, finding the difference between two numbers. It's like having a pile of candies and figuring out how many you have left after you've eaten a few. Just like addition, subtraction is a fundamental skill that’s used in everyday life, from calculating change at the store to figuring out how much time you have left before your favorite show starts. We’ll go through each problem step by step, making sure you understand the process completely. So, let’s get subtracting and see what we can discover!

45 - 30 =

First up, we have 45 - 30. This one's a great starting point because it's pretty straightforward. We start by looking at the ones place: 5 - 0. That's nice and easy – 5 minus 0 is still 5. No borrowing needed here! Now, we move on to the tens place: 4 - 3. That’s also pretty simple, right? 4 minus 3 gives us 1.

Here’s the breakdown to make sure we’re all on the same page:

  • Ones place: 5 - 0 = 5
  • Tens place: 4 - 3 = 1
  • Combined: 15

So, the correct answer is 15. Problems like this are fantastic for building your foundation in subtraction. They help you get comfortable with the basic process before we move on to more complex problems. Keep practicing these simple subtractions, and you’ll be ready for anything!

51 - 24 =

Alright, let's take on 51 - 24. This problem introduces us to a concept called “borrowing,” which is super important in subtraction when the digit you're subtracting is larger than the digit you're starting with. So, in this case, we're looking at 1 - 4 in the ones place. We can't subtract 4 from 1 directly, so we need to borrow from the tens place. This is a crucial step, so let's make sure we understand it.

Here’s how we break it down:

  • Ones place: We can’t subtract 4 from 1, so we borrow 10 from the tens place. This turns the 5 in the tens place into a 4, and the 1 in the ones place becomes 11. Now we have 11 - 4, which equals 7.
  • Tens place: We borrowed 1 from the tens place, so we now have 4 - 2, which equals 2.
  • Combined: 27

So, the correct answer is 27. Borrowing can seem a bit tricky at first, but it’s a fundamental skill in subtraction. When you practice and understand why you're borrowing, it becomes much easier. The key is to remember that you’re just regrouping the numbers to make the subtraction possible. Keep practicing, and you’ll master borrowing in no time!

94 - 21 =

Now, let’s dive into 94 - 21. This subtraction problem is another straightforward one that will help us solidify our skills. We'll start with the ones place, just like before: 4 - 1. What does that give us? That's right, it's 3. Now, let’s move on to the tens place: 9 - 2. Easy peasy, that gives us 7.

Here’s the step-by-step breakdown:

  • Ones place: 4 - 1 = 3
  • Tens place: 9 - 2 = 7
  • Combined: 73

So, the correct answer is 73. This kind of problem is great for reinforcing the basic subtraction process without the need for borrowing. It helps you get really comfortable with subtracting smaller numbers from larger ones. The more you practice these, the better you’ll become at recognizing when you need to borrow and when you don’t. Keep it up, and you’ll be a subtraction whiz!

63 - 45 =

Let's tackle 63 - 45. This problem is another excellent opportunity to practice our borrowing skills. In the ones place, we have 3 - 5. Can we subtract 5 from 3? Nope, we need to borrow! We're going to borrow 10 from the tens place, which will change our 3 into 13. This is where the magic happens in subtraction, so let's walk through it carefully.

Here’s the breakdown:

  • Ones place: We can’t subtract 5 from 3, so we borrow 10 from the tens place. This turns the 6 in the tens place into a 5, and the 3 in the ones place becomes 13. Now we have 13 - 5, which equals 8.
  • Tens place: We borrowed 1 from the tens place, so we now have 5 - 4, which equals 1.
  • Combined: 18

So, the correct answer is 18. Borrowing is such a key part of subtraction, especially when the numbers get larger. It’s like having a secret weapon that allows you to tackle any subtraction problem. The more you practice these types of problems, the more confident you'll become. So, keep at it, and you’ll be subtracting like a pro in no time!
