    Math Symbols List

    List of all mathematical symbols and signs – meaning and examples.

    ∩ The symbol ∩ means intersection. Given two sets S and T, S ∩ T is used to denote the set {x|x ∈ S and x ∈ T}. For example {1,2,3}∩{3,4,5} = {3}. \ The symbol \ means remove from a set.

    Important Algebraic Formula Definition and Examples

    Here is a list of Algebraic formulas –

    a2 – b2 = (a – b)(a + b)
    (a + b)2 = a2 + 2ab + b2
    a2 + b2 = (a + b)2 – 2ab
    (a – b)2 = a2 – 2ab + b2
    (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca
    (a – b – c)2 = a2 + b2 + c2 – 2ab + 2bc – 2ca
    (a + b)3 = a3 + 3a2b + 3ab2 + b3 ; (a + b)3 = a3 + b3 + 3ab(a + b)
    (a – b)3 = a3 – 3a2b + 3ab2 – b3 = a3 – b3 – 3ab(a – b)
    a3 – b3 = (a – b)(a2 + ab + b2)
    a3 + b3 = (a + b)(a2 – ab + b2)
    (a + b)4 = a4 + 4a3b + 6a2b2 + 4ab3 + b4
    (a – b)4 = a4 – 4a3b + 6a2b2 – 4ab3 + b4
    a4 – b4 = (a – b)(a + b)(a2 + b2)
    a5 – b5 = (a – b)(a4 + a3b + a2b2 + ab3 + b4)
