His works, especially the most famous one, the, False, because the correct statement is: In his book, Brahmagupta showed his calculation of the Earth's circumference; his result was, False, because the correct statement is: According to him, positive and negative numbers can be viewed as. Therefore they are supplementary. a ) Brahmagupta established rules for working with positive and negative numbers, such as: adding two negative numbers together always results in a negative number. She also has certificates in University Teaching and Learning and Teaching Online Program from the University of Calgary. sin {\displaystyle a^{2}-b^{2}} ) = A triangle may be regarded as a quadrilateral with one side of length zero. Remarkably, he set his complex math and science ideas out in a book composed entirely in metered poetic verse!
