So because the greater than sign does not look like an L, it can never be “less than”. It shows that one number or value is larger than another number. With math, you usually have to solve the problem, but when using the greater than and less than signs, you’re showing if a number is greater than or less than another number rather than actually solving a problem. The two signs are signs that are used when you’re comparing two things in math. The word “inequality” means that two things are not equal. Inequalities compare two things, showing the relationship between them. These signs are used when math problems don’t have a clear answer, which are also called inequalities. This is the only difference between "<" and "≤".Do you remember learning in school about the little sideways signs that look like little arrowheads:Ī lot of us know that these signs mean “greater than” and “less than”, but can’t seem to remember which sign is which. Unlike the less than sign, ≤ does not denote a strict inequality. This can also be read as meaning that the value or expression on the left hand side of the symbol can at most be equal to the value on the right, never greater. ![]() The less than or equal to sign is a symbol that indicates that the value on the left hand side of the symbol is either less than, or equal to the value on the right. If we want to denote that a can be less than or equal to b, we would use the less than or equal to sign (≤) instead. The value of a must be less than that of b. The following are valid uses of the less than sign: ![]() It indicates a strict inequality between two values specifically, the value on the left of the less than sign is smaller than the value on the right. The less than sign is the counterpart to the greater than sign. This is the only difference between ">" and "≥". This is because ≥ does not denote a strict inequality. GivenĪ can equal b, unlike the greater than sign. This can also be read as the value on the left hand side is at least equal to the value on the right. The greater than or equal to sign is a symbol that indicates that the value on the left hand side of the symbol is either greater than, or equal to the value on the right. In cases where a can also equal 4, we would use the greater than or equal to sign instead. Thus, if b were 4, a could be any value above 4, but not 4. The following are valid uses of the greater than sign:Ī must be greater than b. Greater than is a strict inequality, meaning that the value on the left of the sign must be greater than the value on the right they cannot be equal. The greater than sign is a symbol that indicates a strict inequality between two values specifically, that the value to the left of the greater than sign is larger than the value on the right. There are other, more specific inequality relations, like those below. While the above use of ≠ is true for all the cases, it doesn't tell us much other than that the expressions on either side of the symbol are not equal. The not equal to sign, also referred to as the does not equal sign, is a symbol that indicates the inequality of the values or expressions on either side of the symbol. In cases where the values are not equal, we can use a number of different inequality symbols, such as the not equal to sign. Equality (as well as inequality) is a basis for solving algebraic equations and inequalities.Īll of the above equations are true. Expressions on either side of an equals sign either have the same value, or have the same value for certain values. The equals sign, symbolized as "=" indicates equality. Although an equals sign is not technically an inequality symbol, it is discussed together with inequality symbols since it is included as part of non-strict inequalities such as greater than or equal to (≥) and less than or equal to (≤). If the character does not have an HTML entity, you can use the decimal (dec) or hexadecimal (hex) reference. Strict inequalities include less than () symbols, described below. If you want any of these characters displayed in HTML, you can use the HTML entity found in the table below. ![]() Together with other mathematical symbols such as the equals sign (=), which indicates an equality relation, they are sometimes referred to as relation symbols. Inequality symbols are symbols that are used to indicate inequality relations. Home / algebra / inequality / inequality symbols Inequality symbols
