so we should be using the individual interfaces: ```csharp public readonly struct Angle<T> : IE

public readonly struct Angle<T> 
    : IEquatable<Angle<T>>
    , IEqualityOperators<Angle<T>,Angle<T>, bool>
    , IComparable<Angle<T>>
    , IComparisonOperators<Angle<T>,Angle<T>, bool>
    , IAdditionOperators<Angle<T>,Angle<T>,Angle<T>>
    , IDivisionOperators<Angle<T>, T, Angle<T>>
    , IDivisionOperators<T, Angle<T>, Angle<T>>
    , IMultiplyOperators<Angle<T>, T, Angle<T>>
    , IMultiplyOperators<T, Angle<T>, Angle<T>>
    , IModulusOperators<Angle<T>, Angle<T>, Angle<T>>
    , ISubtractionOperators<Angle<T>,Angle<T>,Angle<T>>
    where T : IFloatingPointIeee754<T>
