So in this scenario, the “equal to” sign is the best fit:Īll images/mathematical drawings were created with GeoGebra.The Latin root word equ means “equal.” Soon enough you will learn to equate equ with “equal”-especially since the meaning of the root equ, “ equal,” contains the root itself! It has been explained above that when we compare two quantities, and they are the same, we use the “equal to” sign. If we suppose mathematically that the total cost of 5 apples is exactly the same as that of 3 oranges, then which sign will best fit? Solution Solved Problems Involving the Equal Symbol Example The term “equation” may also direct to an equality relation that is satisfied exclusively for the values of the variables that one is keen on. To find the values of some variables, called unknowns, an equation is used, for which the specified equality is true. At the point when these phrases are joined with one another, they make another phrase, “ Greater Than Or Equal To.” This phrase is used to express that the quantity or amount value could actually be equal to or greater than the given limit. ‘is equal’ term shows that two numbers are equal. It is used to show that one number is greater, in any sense, than the other number. It means that the number is either equal to or greater than a certain value. it can also be defined as no more than, at most, not exceeding, and a maximum of.ģ $\leq$ 3 Greater Than or Equal To ($\geq$) It means a number is either equal to or less than another number. $\bigtriangleup$ ABC $\cong\bigtriangleup$ DEF Less Than or Equal To ($\leq$) Generally, the congruent symbol is used in an expression like this: The ≅ (congruent) symbol in geometry is utilized to show that two shapes are identical to each other in size and shape. Generally, the symbol is used in an expression like this: The approximate symbol shows that the two values are approximately the same to each other. X $\equiv$ y(mod N) Approximation ($\approx$) Generally, the equivalent symbol is used in an expression like this:

The equivalent sign is used in modular arithmetic to show that two given numbers are congruent modulo any number N. Symbols Related To Equalityįollowing are the symbols that are associated with equality, Not Equal To ($\neq$)Īs the sign suggests, the not equal symbol in math means that the two expressions are not equal to each other.

Although the symmetric and transitive properties are usually looked at as elemental, they can also be deduced from the properties of substitution and reflexive. They were initially counted among the Peano axioms for natural numbers. The above three properties justify equality as an equivalence relation.

Transitive property: For any values of a, b, and c, if a = b and b = c, then a = c.

Symmetric property: For any values of a and b, if a = b, then b = a.

Reflexive property: For any value of a, a = a.

Some specific examples are: a) For any real numbers a, b, and c, in the event that a = b, then a + c = b + c.ī) For any real numbers a, b, and c, in the event that a = b, then a − c = b − c.Ĭ) For any real numbers a, b, and c, in the event that a = b, then ac = bc.ĭ) For any real numbers a, b, and c, in the event that a = b and c is a non-zero, then a/c = b/c.

Substitution property: For any given values x and y and any given expression F(x), if x = y, then F(x) = F(y) (given that both sides are well-formed).

The Basic Properties of the Equation are listed below:
