why this sign is reversed
Answers
≠ not equal sign inequality 10 ≠ 6
= equals sign equality 3 = 1 + 2
< strict inequality less than 7 < 10
> strict inequality greater than 6 > 2
≤ inequality less than or equal to x ≤ y, means, y = x or y > x, but not vice-versa.
≥ inequality greater than or equal to a ≥ b, means, a = b or a > b, but vice-versa does not hold true.
