A number line with positive numbers 0, 1, 2, 3, 4 marked on the right, and the left side fading out in a maths-class style.

A clean, simple number line running horizontally. The positive numbers are shown clearly on the right side. On the left side of the number line, where the negative numbers would normally be, the line suddenly stops or fades out as if someone ‘refused’ to draw the negative part. Use a light, friendly maths-class style. See more
