Solving The Sum Of 1 Ten And 18 Units A Detailed Explanation
Hey everyone! Today, let's dive into a math puzzle that's got everyone scratching their heads. We're going to break down the question, "What number do you get when you add 1 ten and 18 units?" and figure out the right answer together. Math can be like a fun game if we know the rules, so let's jump in and solve this!
Decoding the Question
Before we even start adding numbers, it's super important to understand what the question is asking. Sometimes, math problems use words that can be a bit confusing if we don't break them down. So, let's take a closer look at our question:
"What number do you get when you add 1 ten and 18 units?"
- 1 ten: This part is talking about the number 10. Think of it like a group of ten things, like ten fingers or ten candies. So, when we see "1 ten," we know we're dealing with the number 10.
- 18 units: This is a straightforward way of saying the number 18. "Units" just means individual items or ones. So, "18 units" means we have 18 individual things.
- Add: This is our key action word! It tells us we need to combine the two numbers we've identified. Adding means we're putting things together to find the total.
Now that we've decoded the question, it's much clearer what we need to do. We need to add 10 (1 ten) and 18 (18 units) together. This is where the fun begins!
Breaking Down the Numbers
Before we add, let's break down the numbers a bit more. This can help us see how the addition works and make sure we get the right answer.
- 10: This number is made up of 1 ten and 0 ones. It's a neat, tidy number that's easy to work with.
- 18: This number is made up of 1 ten and 8 ones. We can think of it as a group of ten and then eight extra individual units.
Seeing the numbers in this way can make the addition process smoother. We can imagine combining the tens and then adding the ones. It's like building with blocks – we're putting together groups and individual pieces.
The Addition Adventure
Now comes the exciting part – the addition! We're going to combine 10 and 18 to find our mystery number. There are a few ways we can do this:
- Counting On: Start with the bigger number, 18, and then count on 10 more. We can do this by thinking, "18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28." This method works well, but it can take a bit of time if we're adding larger numbers.
- Using Place Value: Remember how we broke down the numbers into tens and ones? We can use that to add them up. We have 1 ten from the 10 and 1 ten from the 18. That gives us 2 tens, which is 20. Then, we have 0 ones from the 10 and 8 ones from the 18. That gives us 8 ones. So, we have 20 + 8, which equals 28.
- Mental Math: If we're feeling confident, we can try to do the addition in our heads. We know 10 + 10 is 20, and then we just need to add the extra 8 from the 18. This gives us 28 again.
No matter which method we use, we should arrive at the same answer. And that answer is 28! So, the number we get when we add 1 ten and 18 units is 28.
Choosing the Right Answer
Now that we've done the math, let's look at the answer choices and pick the correct one.
The question gives us these options:
A) 28 B) 38 C) 18 D) 10
We already figured out that the answer is 28, so the correct choice is A) 28. We did it!
Why the Other Options Aren't Right
It's always a good idea to think about why the other answer choices are incorrect. This helps us understand the problem better and avoid making mistakes in the future.
- B) 38: This number is too big. It's like we added an extra ten somewhere. We only had 1 ten and another 1 ten, so we shouldn't end up with 3 tens.
- C) 18: This is just the number of units we started with. We forgot to add the 1 ten, so this answer is too small.
- D) 10: This is the value of 1 ten, but we didn't add the 18 units. So, this answer is also too small.
By understanding why these options are wrong, we can be more confident that our answer of 28 is correct. It's like being a detective and solving a mystery – we're looking for clues and ruling out possibilities until we find the truth!
Wrapping Up: Math is an Adventure!
So, guys, we've cracked the code and found the mystery number! We took a math question, broke it down into smaller pieces, and used our math skills to solve it. We learned that adding 1 ten and 18 units gives us 28. And we didn't just find the answer – we understood why it's the right answer.
Math might seem tricky sometimes, but it's really like an adventure. We have to explore, use our tools (like addition and place value), and think carefully. And when we solve a problem, it feels awesome!
Keep practicing, keep exploring, and keep having fun with math. You're all math superstars in the making!
The correct answer is A) 28. Here's a detailed explanation of how we arrived at this answer:
