In mathematics, when comparing two numbers on the number line, the number closer to zero is considered bigger. In this case, -7 is bigger than -8 because it is closer to zero on the negative side of the number line. This is because as you move to the right on the number line, the numbers increase in value, and as you move to the left, the numbers decrease in value.
