    The square of a number increased by 7 is 23

    The phrase a number means an arbitrary variable, let's call it x.
    x

    The square of a number means we raise x to the power of 2:
    x^2

    Increased by means we add 7 to x^2
    x^2 + 7

    The word is means an equation. So we set x^2 + 7 equal to 23:
    x^2 + 7 = 23
