Why is homework given to students?
Homework teaches students to work independently and develop self-discipline. Homework encourages students to take initiative and responsibility for completing a task. Homework allows parents to have an active role in their child’s education and helps them to evaluate their child’s progress.
Who was 0?
“Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628,” said Gobets. He developed a symbol for zero: a dot underneath numbers. “But he, too, does not claim to have invented zero, which presumably must have been around for some time,” Gobets added.
What was used before zero?
Some of the first known zero symbols appear in Babylonian clay tablets of between 400 and 300 B.C.; there the zero was used to clarify the symbols for large numbers. Brahmagupta was the first to write down the rules for arithmetic with zeros.
What if zero was not invented?
Without zero, modern electronics wouldn’t exist. Without zero, there’s no calculus, which means no modern engineering or automation. Without zero, much of our modern world literally falls apart.
