It looks like 21/2, though I am not sure what I can say about why!
"billion" = 109"trillion" = 1012"billion trillion" = 1021

21 zeroes: 1,000,000,000,000,000,000,000
6,300,000,000,000 (6.3 trillion).

Trillion has 12 zeroes like 3,000,000,000,000 Next to trillion is quadrillion with 15 zeroes then quintillion with 18 zeroes then sextillion with 21 zeroes
"billion" = 109"trillion" = 1012"billion trillion" = 1021
The trisomy 21 in a karyotype would look like extra chromosome 21 I ^^

21 trillion AU
21/2=10.5 So 10.5 is the half of 21
