Sultan, On Mathematics!
Let me correct, Mathematics was not invented but was discovered (intellectual still debate on it)rather progressed by time.
Noone can claim having found/invented/discovered it alone, it belong to all old civilizations-Indus/Chinese/Nile/Greek/Arabs etc.
Major Indian contribution was number system & Decimal(dashmalav in Indic/Vedic) and that is regarded as fundamental chnage in mathematics. Arabs discovered Al-jebra. Even today you can find arab numerals are owed by Indian/Vedic numeral system and so on.
Now dont fight with me Plz. When you come here, visit any museum and you'll find it.
