A number line is a visual representation of numbers on a straight horizontal line. By using this tool, you can easily compare values, including integers. The number line includes positive numbers, negative numbers, and zero.
Every number on the number line has a specific position. Positive numbers are always placed to the right of zero, while negative numbers are to the left.
When plotting numbers on the number line, ensure you have a proper scale so that each segment between consecutive integers is evenly spaced. This helps in making accurate comparisons.

Negative numbers are less than zero and are always found to the left of zero on the number line.
These numbers represent values below zero or opposite in their numerical distance from positive numbers.
When comparing negative numbers with each other, keep in mind that a larger negative number is actually smaller. For instance, -4 is less than -3, even though the absolute value of 4 is greater than 3.
This concept can be tricky because we often think of larger numbers as greater, but with negatives, the opposite is true. In general, the further to the left on the number line, the smaller the number.

Comparing integers involves determining which number is greater, less, or if they are equal. The number line is an essential tool for visualizing this.
For positive integers, the further right on the number line, the greater the number. Conversely, for negative integers, the further left, the smaller the number. An important fact is that any positive integer is greater than any negative integer.
When given a comparison such as '-4 > -3', you can use the number line to accurately assess the statement. Since -4 is to the left of -3 on the number line, -4 is less than -3. Therefore, the correct comparison should actually be '-4 < -3'. Visualizing these comparisons helps reinforce understanding and ensures accurate conclusions.
