In mathematics , an inequality is a relation that holds between two values when they are different see also: equality. If the values in question are elements of an ordered set , such as the integers or the real numbers , they can be compared in size. In contrast to strict inequalities, there are two types of inequality relations that are not strict:. In engineering sciences, a less formal use of the notation is to state that one quantity is "much greater" than another, normally by several orders of magnitude. This implies that the lesser value can be neglected with little effect on the accuracy of an approximation. For example, the ultrarelativistic limit in physics.

Equal, Greater or Less Than
Did you know that we started using the equal sign more than years ago? The first to do so was the doctor and mathematician Robert Recorde, who explained that there are no two things that may be more equal than two parallel lines. So he began to use this symbol to represent equality:. There are other symbols that we can use to indicate relationships between numbers: the inequality symbols! With them, we can make comparisons. This trick can help you to know which way it should be rotated:. The large opening always points to the greater value, and the smaller end, the tip, toward the smaller value.
When two values are definitely not equal we use the "not equal to" sign. When one value is smaller than another we use a "less than" sign. When one value is bigger than another we use a "greater than" sign. The "less than" sign and the "greater than" sign look like a "V" on its side, don't they? It could be 4 cups or it could be less than 4 cups: So until we measure it, all we can say is "less than or equal to " 4 cups. To show this , we add an extra line at the bottom of the "less than" or "greater than" symbol like this:. Always make sure the small end points to the small value.
In mathematics, an inequality is a relation that holds between two values when they are The notation a ? b or a ? b means that a is less than or equal to b (or, greater than" can also be represented by a ? b, the symbol for "greater than".
