The modern decimal point became the standard in England in Algebra and the Pythagoras' theorem both originated in India but the credit for these has gone to people from other countries, Union Minister for Science and Technology, Harsh Vardhan, said on Saturday.
Vardhan said. When was algebra invented? So algebra was invented in the 9th century. Trigonometry in the modern sense began with the Greeks. Hipparchus c. So zero divided by zero is undefined. Just say that it equals "undefined. We can say that zero over zero equals "undefined.
Real numbers are, in fact, pretty much any number that you can think of. Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers. It fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures.
Rounding in decimals works identically to rounding with whole numbers: if the number immediately to the right of the target is 5 or more, round up by making the target value one greater and then change the rest of the numbers to the right of the target to zero; otherwise, round down by keeping the target number the ….
To have four decimal places is to have four or fewer digits to the right of the decimal point when written in decimal notation e. Typically we would pad a number with fewer than four digits, so 1. The first digit after the decimal point is called the tenths place value.
There are six tenths in the number O. For instance, the number A suitable rule specifies up to one decimal place and up to two significant digits. When comparing group means or percentages in tables, rounding should not blur the differences between them. Begin typing your search term above and press enter to search.

Cryptic phrases called sutras contained arithmetical rules for activities such as laying out a temple or arranging a sequence of sacrificial fires. Large numbers held immense fascination. Acclamations of praise to the air, sky, times of day or heavenly bodies were expressed in powers of ten that went to a trillion or more.
Reputedly, the young Prince Buddha successfully competed for the hand of Princess Gopa by reciting a number table that included names for the powers of ten beyond the twentieth decimal place.
As in other early agricultural civilizations, Indian mathematics probably emerged in response to the need to measure land areas and keep track of financial transactions, incomes and taxation. A rigid caste and class hierarchy reserved the mystery of numbers for elite Brahmins. To maintain personal power, mathematical knowledge was jealously guarded.
The book details the impressive achievements of Indian mathematicians, from Aryabhatta through Brahmagupta, Mahavira, Bhaskara and Madhava, until the Sanskrit tradition became irrelevant with the invasion of modern mathematics from Europe in the nineteenth century. Major discoveries include finding the solution to indeterminate equations and the development of infinite series for trigonometric quantities.
Discovered in the fourteenth century by the Kerala school founded by Madhava, these series built on the work of Bhaskara II and grew from the ingenious computation of a circle's circumference. By breaking up the circle into polygons, Madhava was able to calculate the value of pi correct to 11 decimal places. Some developments preceded those in Europe. For example, Reuben Burrow — a British mathematician posted to Bengal as an instructor in the engineers corps — was intrigued by rules he discovered in an unnamed Sanskrit text, and wrote a paper in entitled 'A Proof that the Hindoos had the Binomial Theorem'.
But how peculiarly Indian was early Indian mathematics? Did it evolve in isolation or did it absorb ideas and knowledge from elsewhere? Cultural pride in their recently reinvigorated country causes some Indians to claim that all worthwhile mathematics originated in ancient India.
But this book will not please them. For example, when we calculate our weight on the weighing machine, we do not always find the weight equal to a whole number on the scale. Decimal fractions were first developed and used by the Chinese in the end of 4th century BC, and then spread to the Middle East and from there to Europe. Notably, the polymath Archimedes c. His slide ruler invention U.
