Which of the students is correct
Let a number be x,
Given what the teacher asked the students to do, the solution is:
![Number = x](https://tex.z-dn.net/?f=Number%20%3D%20x)
![Opposite = -x](https://tex.z-dn.net/?f=Opposite%20%3D%20-x)
![Absolute = |x|](https://tex.z-dn.net/?f=Absolute%20%3D%20%7Cx%7C)
Only Sarah got this correctly; others are incorrect.
The proof is as follows.
For Sarah
![Number = 1416](https://tex.z-dn.net/?f=Number%20%3D%201416)
![Opposite = -1416](https://tex.z-dn.net/?f=Opposite%20%3D%20-1416)
![Absolute =|1416| = 1416](https://tex.z-dn.net/?f=Absolute%20%3D%7C1416%7C%20%3D%201416)
So, the numbers will be: 1416, -1416 and 1416
