• Born in the city of Bhinmal , which is presently known as North West
Rajasthan…
• Born in 598, passed away in the mid to late 600’s.
• Known as the “Father Of Zero.”
• Accredited to inventing the concept of zero. Brahmagupta describes about
Zero as one of the numerals which stood for meaning nothing.
• Not only was he a mathematician, he was the leader of astronomical research in ancient India.
• A debt minus zero is a debt.
• A fortune minus zero is a fortune.
• Zero minus zero is a zero.
• A debt subtracted from zero is a fortune.
• A fortune subtracted from zero is a debt.
• The product of zero multiplied by a debt or fortune is zero.
• The product of zero multiplied by zero is zero.
• The product or quotient of two fortunes is one fortune.
• The product or quotient of two debts is one fortune.
• The product or quotient of a debt and a fortune is a debt.
• The product or quotient of a fortune and a debt is a debt.
• In his theorem he explains different uses of the concept of zero. Which he uses debt and fortunes, what we recall today negative and positive numbers.
• For example a debt minus a zero is a debt, in other words a negative number subtracted from a zero, the result will be a negative.
• The number zero, multiplied or divided by a negative or positive number, will give you a zero as an result.
• Brahmagupta’s concept of zero, was not all the way complete.
• How is that?
• He stated that anything divided or multiplied by zero will equal zero.
• Not until five hundred years later, Bhaskara II proved
Brahmagupta wrong.
• Bhaskara II said that anything divided by the number zero will not equal to zero but infinity instead.
• Not only did Brahmagupta invent the concept of zero, he also studied quadratic equations..
• For instance, (x2+6x-8=0). This equation could have two possible solutions, one as a negative number and the other result as a positive number.
• In mathematics today, we use the concept of the quadratic equation in our everyday math lives. Classes such as Pre-
Calculus, Algebra, and high level calculus courses all use this formula.
• And as for the concept of zero. It helps us define the absence of existence in our everyday lives.
