    The insertion rules

    The following operations can be performed

    - multiplication
    - division
    - squaring
    - cubing
    - raising to the power
    x + 7
    - addition
    x - 6
    - subtraction
    Real numbers
    insert as 7.5, no 7,5


    - number Pi
    - the base of natural logarithm
    - complex number
    - symbol of infinity
