Step-by-step explanation:
The number line is a line with marks, where each mark represents a real number.
In the vertical number line zero is in the center. The numbers above zero are considered positive and the numbers below zero are considered negative.
4
3
2
1
0
-1
-2
-3
-4
The numbers after zero start from 0, 1, 2 ...... and 0, -1, -2.....
Hence, Carlos is wrong and -4 is further to zero than -2
