How old am I? I was born in 2004 my birthday is in March 7.

A. 9

B. 10

C. 13

D. 14

You are 13 years old. We can figure this out by simply subtracting 2004 from 2017 (the current year). If you had not had your birthday yet, we would solve this by subtracting 2004 from the previous year (2016).

2017

-2004

0013

2017 - 2004 = 13 but its past March 3 so D, 14
