If you take the first 13 prime numbers and add them up, you get 238.
2+3+5+7+11+13+17+19+23+29+31+37+41 = 238
But check her name out. (The numbers represent the letter in the alphabet; A=1, B=2, etc.)
Taylor Alison Swift = (20+1+25+12+15+18) + (1+12+9+19+15+14) + (19+23+9+6+20) = 91+70+77 = 238. Is that a coincidence or did it happen on purpose?
