Algebra Symbols in Maths
Algebra is that branch of mathematics that helps us to find the value of unknown. The unknown value is represented by variables. Various operations are carried out to find the value of this unknown variable. Algebraic Symbols are used to represent the operations required for the calculation. Symbols used in Algebra are illustrated below:
Symbol | Name | Description | Meaning | Example |
---|---|---|---|---|
x, y | Variables | unknown value | x = 2, represents the value of x is 2. | 3x = 9 β x = 3 |
1, 2, 3β¦. | Numeral constants | numbers | In x + 2, 2 is the numeral constant. | x + 5 = 10, here 5 and 10 are constant |
β | Inequation | is not equal to | If a β b, a and b does not represent the same number. | 3 β 5 |
β | Approximately equal | is approximately equal to | If a β b, a and b are almost equal. | β2β1.41 |
β‘ | Definition | is defined as βorβ is equal by definition | If a β‘ b, a is defined as another name of b | (a+b)2 β‘ a2+ 2ab + b2 |
:= | If a := b, a is defined by b | (a-b)2 := a2-2ab + b2 | ||
β | If a β b, a is definition of b. | a2-b2β (a-b).(a+b) | ||
< |
| is less than | If a < b, a is less than b | 17 < 45 |
> | is greater than | If a > b, a is greater than b | 19 > 6 | |
<< | is much less than | If a < b, a is much less than b |
1 << 999999999 | |
>> | is much greater than | If a > b, a is much greater than b |
999999999 >> 1 | |
β€ |
| is less than or equal to | If a β€ b, a is less than or equal to b | 3 β€ 5 and 3 β€ 3 |
β₯ | is greater than or equal to | If a β₯ b, a is greater than or equal to b | 4 β₯ 1 and 4 β₯ 4 | |
[ ] |
| Square brackets | calculate expression inside [ ] first, it has least precedence of all brackets | [ 1 + 2 ] β [2 +4] + 4 Γ 5 = 3 β 6 + 4 Γ 5 = 3 β 6 + 20 = 23 β 6 = 17 |
( ) | parentheses (round brackets) | calculate expression inside ( ) first, it has highest precedence of all brackets | (15 / 5) Γ 2 + (2 + 8) = 3 Γ 2 + 10 = 6 + 10 = 16 | |
β | Proportion | proportional to | If a β b , it is used to show relation/ proportion between a and b | x β yβΉ x = ky, where k is constant. |
f(x) | Function | f(x) = x, is used to maps values of x to f(x) | f(x) = 2x + 5 | |
! | Factorial | factorial | n! is the product 1Γ2Γ3β¦Γn | 6! = 1 Γ 2 Γ 3 Γ 4 Γ 5 Γ 6 = 720 |
β | Material implication | implies | A β B means that if A is true, B must also be true, but if A is false, B is unknown. | x = 2 βx2 = 4, but x2= 4 β x = 2 is false, because x could also be -2. |
β | Material equivalence | if and only if | If A is true, B is true and if A is false, B is also false. | x = y + 4 β x-4 = y |
|β¦.| | Absolute value | absolute value of | |a| always returns the absolute or positive value | |5| = 5 and |-5| = 5 |
Maths Symbols β Basic Mathematics Symbols
Maths symbols are figures or combinations of figures that represent mathematical objects, actions, or relations. They are used to solve mathematical problems quickly and easily.
Foundation of mathematics lies in its symbols and numbers. The symbols in mathematics are used to perform various mathematical operations. The symbols help us to define a relationship between two or more quantities. This article will cover some basic Math symbols along with their descriptions and examples.
