      say it asked you to round to the nearest ten and the number is 17.

      since 17 is closer to twenty than it is to ten, 17 rounded to the nearest ten is 20.
      if the number where 14 instead of 17, rounded to the nearest ten it would be 10.
      if a number were to be rounded to the nearest hundred. say the number is 60, then the answer would be 100. if it where 48, it would be 0.

    Rate my essay In the Civil war over 700,000 died. Today I will be teaching you about the Civil war. My subtopics are Family, food and population. Even though a lot of people joined, not a lot came out. In the battle of Cold Harbor in twenty minutes 7000 people fell to their deaths. (According to the book The Boys War) Almost 2 percent of the population died in this horrific war.
    Family and friends

    When you're in war and you're far from home and all you can think about is your family. (In the book The Boys War it said) “imagine having your son go to war and he comes back and you don’t even remember him.” Imagine your son went missing and you figured out he snuck to war and died, that would be sad. People’s families' kids were forced to go to war, and the parents and friends figured that if they died they would be sad. Family’s houses were captured and used as bases.

    Food
    Imagine being in war and really needing food and it costs a lot and you do not have enough money so you can’t eat for a week. When people were in the war, it took two weeks to get food. So that means low energy and starvation, and if they're low on energy they can’t fight. And when it takes two weeks to get it you're low on food. Food cost about 10 to 15 dollars$ and that was a lot back then compared to now. (According to the book called The Boys War) Back then they were eating raw meat because they didn’t have the storage to carry pots and pans.
    Population
    (According to the book The Boys War 2% of people died and that affected soldiers' friends and family.) That's over 700,000 people. So many people had died so some people were walking over bodies in the war. Right after they were done with 1 part of the war people were non stop digging graves for the dead. It was a hard time for a lot of people seeing everyone dead.
    Conclusion

    In summary, I taught you about the Civil War. My subtopics were Family and friends, food and the population. If you want to learn more about the Civil War read the book The Boys War. Or search facts about the Civil War. Search the Wikipedia for even more information.

Video transcript

- [Instructor] So we have four numbers listed here, and what I would like you to do is get out some pencil and paper and pause this video and see if you can order these numbers from least to greatest. So the least would be at the left, and then keep going greater, and greater, and greater until you get to the greatest number. So pause the video and have a go at that. All right, now let's tackle this together. And the way that I like to do it is I start at the, I guess you could say, the most significant place value or the largest place value, compare the numbers. And then keep moving to the right to smaller and smaller place values. So we can start in the ones place. This number has zero ones, this number has zero ones, this number has zero ones, and that number has zero ones. So the ones place really doesn't help us much. But then we can move to the tenths place. This number has 7/10. This number has 0/10, so just from that we know that the second number is less than the first number. This has 7/10, this has 0/10. It doesn't matter what's happening in the places after that, to the right of that. This number over here also has 7/10, just like the first number. And this last number also has 7/10. So we know from comparing the ones and then the tenths place is that this number right over here is the smallest of the four numbers. They all have zero ones, but this one also has 0/10. So I'll list that here, 0.074. Now let's move to the hundredths place. So this number has 0/100. We've already used this number. This number has 7/100. And then this number, it might not be obvious, but the hundredths place you can view as being zero, the hundredths place, you can just put a zero there and not change the value. So this also has 0/100. So these three numbers, same ones, same tenths, but this number, 0.77, has 7/100, while the other two had 0/100. So this is going to be the largest of our four numbers. This is larger than these other two because of what we see in the hundredths place. It doesn't matter what's happening in the thousandths place or anything beyond that. So we put the 0.77 right over there. And now we are tasked, and we've used this number, and now we have to compare these two numbers, which were equal in the ones, tenths, and hundredths place, so we have to go to the thousandths place. This number has 7/1000. This number has 0/1000. So this number is smaller than this first number here. So I'll write this next, 0.7, and then the third smallest, or the next to largest number is this one over here, 0.707, and we're done. So the main idea is you wanna compare the most significant place values, the largest places values first, and then based on that, keep moving to the right to compare less and less significant place values.
