Find the Relationship Between Points I(3) and C(-3) on Number Line

Q: Why is 3 greater than -3 when they look the same?

The sign makes all the difference! The number 3 is positive (above zero), while -3 is negative (below zero). On a number line, numbers get larger as you move right.

Q: How can I remember which direction means greater?

Think of a thermometer! Higher temperatures are warmer, and they're found above lower temperatures. On a horizontal number line, greater numbers are to the right.

Q: Do I need to calculate anything for these problems?

No calculation needed! Just identify the values from the number line, then remember that positive numbers are always greater than negative numbers.

Q: What if both numbers were negative?

When both numbers are negative, the one closer to zero is greater. For example, -2 > -5 because -2 is closer to zero on the number line.

Common Mistakes

Avoid these frequent errors

Comparing absolute values instead of actual values
Don't compare |3| and |-3| and say they're equal = wrong comparison! This ignores the crucial difference between positive and negative values. Always compare the actual numbers with their signs included.
