Number line in Math
Integer consists of:
- negative integer,
- zero integer,
- positive integer.
On the number line, integers can be represented as follows.
- Numbers to the left of zero are negative integers, the farther to the left the value is smaller.
- Numbers to the right of zero are positive integers, the greater the value to the right.
Let's pay attention to the following demonstrations.
1. For example, you are in number 2 facing right. Then you move 4 units to the right. What number are you at now?
2. A chick is at number 5, then steps to the left as far as 8 units. What number are the chicks now?
