on a number line when we add a negative integer

On a number line, when we add a negative integer, we move to the left. This is because adding a negative number means decreasing the value, so starting from the initial point on the number line, you count the number of units to the left equal to the absolute value of the negative integer. For example, if you start at 3 and add -4, you move 4 steps to the left, landing at -1. This movement to the left indicates the reduction in value on the number line when adding negative integers.
