Find the Missing Mathematical Sign: 3 ? 0 Operation

Q: How do I remember which way the inequality sign goes?

Think of the inequality sign as a hungry mouth that always wants to eat the bigger number! The symbol $ > $ opens toward 3 because 3 is larger than 0.

Q: Is there a trick to compare positive and negative numbers?

Yes! Positive numbers are always greater than zero, and zero is always greater than negative numbers. So any positive number like 3 is automatically greater than 0.

Q: Can I use a number line to help me?

Absolutely! On a number line, numbers get bigger as you move right. Since 3 is to the right of 0, we know $ 3 > 0 $.

Q: What if I'm comparing two negative numbers?

The same rules apply! The number closer to zero is always greater. For example, $ -2 > -5 $ because -2 is closer to 0 on the number line.

Common Mistakes

Avoid these frequent errors

Confusing which direction the inequality sign points
Don't think that > means 'less than' just because it points left = wrong comparison! The symbol > always opens toward the larger number like a mouth eating the bigger value. Always remember the symbol 'eats' the larger number.
