ब्राह्मस्फुटसिद्धान्त (ब्रह्मगुप्त - शून्य, कुट्टक, बीजगणित एवं सम्पूर्ण २१ अध्याय सान्वय सटीक)

(line 11): ६. सैकं for (सैक)
Look at that ६: it is open at the top-left, curves down, loops at the bottom and curves up to the right.
Now look at line : the digit in १९०२:
It has a closed loop on the left, curving up and then down to the right: that is precisely ९!
Wait, look at it: yes, it is ९! So the year is १९०२!
1902 AD is when Sudhakara Dvivedi's edition was printed in Benares!
"यह श्लोक १९०२ में बनारस से मुद्रित प्रति में ७८ संख्या पर है"
Wait, let's re-examine that digit:
Could someone read it as १६०२? At first glance, a modern reader might mistake it for ६, but it's clearly १९०२ (1902)!
Wait, let's look closely at १९०२:
Top loop on the left, stroke goes up, then loops down to the right. Yes, that is 100% Devanagari ९.

Let's check the line markers and match the layout line by line.

Line 1: ( २५७ )
Line 2: शशिलिप्ता शेषकृतिर्द्विनवति गुणिता अशिति गुणितं वा ।
