Unequal means not the same in size, amount, value, or quality. When you divide a pizza and one person gets three slices while another gets only one, the portions are unequal. When two teams play and one has twelve players while the other has only six, it's an unequal match.

The word often describes situations where the difference matters or seems unfair. If two students do the same amount of work but receive unequal credit, that's unjust. If a seesaw has an adult on one side and a small child on the other, their unequal weights make it impossible to balance.

Things can be unequal in many ways: unequal lengths of rope, unequal chances of winning, unequal shares of dessert. Sometimes unequal simply means different, like when rock samples have unequal densities. Other times it suggests unfairness, especially when people receive unequal treatment despite deserving the same.

The opposite of unequal is equal, meaning the same or balanced. Mathematics uses the symbols ≠ for “not equal” and = for “equal.” When something is unequal, there's an imbalance or difference that often needs to be recognized, measured, or corrected.
