Here it goes;
MAN + WOMAN = CHILD (Equation 1)
MAN + MAN + WOMAN = INSECURED MAN + HAPPY WOMAN (Equation 2)
MAN + WOMAN + WOMAN = INSECURED WOMAN + HAPPY MAN (Equation 3)
Therefore: Equations 2 & 3 should not be used at any time, either man or woman
Eto ang malufet na equation;
WO.MAN - MAN = W.O. (Equation 4)
Where: W.O. is given the value as
Withdrew
Outright
Withdrawal Method (no matter how fast and outright) will give an absolute value of Zero or 1.
Thus,
WO.MAN - MAN = W.O. = 0 or 1 CHILD
But, the Value of CHILD = 0 or 1 can be affected if the Principle of Withdrawal Method is applied again without the practice.
