but first get a calculator
lets begin:
1-multiply the number of your brothers by 2
(if u dont have any brothers skip this step)
2-add 3 then multiply by 5
3-add the number of your sisters (if no sisters skip)
4-multiply the result by 10
5-add the number of your living grandparents(if no living ones skip)
6-finally substract 150 from the result
now notice that the result consisit of 3 digits
the first one from the right is the nubmer of ur living grandparents the middle one is the number of ur sisters
and the last one is ur brothers
