Ted was not able to believe that a day before he was in his Mathematics class, desperately waiting for it to get over, and then, all of a sudden, he was in the world of numbers which was so interesting.
He asked \13\), “How are the number houses arranged on this number line?”
$13$ replied, “The number houses are arranged in ___ order of the numbers on the number line.”

Solution

Positive numbers were discovered first. And it was known that the largest positive number can’t be found. So, number line started with the numbers we knew already, i.e. $1$ and then $2$ followed by $3$ and so on. After the discovery of $0$ and integers, they were added to the extended number line to the left.

This means that the number on the right side of the number line is one greater than the number before it. So, the number houses are arranged in ascending order of the numbers, as on the number line.

Actually, a number on the number line is greater than all the numbers to its left side.

After playing, Ted remembered that he doesn’t have a home there. Luckily, number 13 was passing by and asked him if he wanted to stay at its place. Having no other option (and surprised that number 13 brought good luck), Ted went with 13. When he reached the house, he was surprised to see that all the houses were placed in a straight line at equal separation. Neighbors of 13 were 12 and 14; similarly14 had 13 and 15 as neighbors. 13 said, “This line, mathematically, is called ______.”

Ted went with number $13$ to his house.There, he was surprised to see that all the houses were placed in a straight line at equal distances. Neighbors of $13$ were $12$ and $14$ ; similarly $14$ had $13$ and $15$ as neighbors. $13$ said, “This line, mathematically, is called a ______.”

Surprised to know that $- 1$ was the largest number here, Ted asked $- 13$ about the smallest number. When it told him to ask $- 14$ about the smallest number, he understood that it is impossible to find the smallest negative integer. To find $0$ , Ted went to its house with $- 13$ and found it was empty.

After that Ted asked $- 13$ about zero. He was shocked when it said that $0$ was kidnapped by the positive integers and that its house has always been empty.
How is this even possible that $0$ is not in the state of positive integers as well as negative integers?

One day Ted woke up to find himself in the world of numbers. He observed that all of them were counting numbers and the smallest one there was $1$ . Ted must be in the world of:
