This won't allow typing superscripts so how do you solve 9.48 x 10 to the 7th X 10to the3rd?
With superscripts, that would be 9.48 x 107 x 103. Add the exponents: 107 x 103 = 1010, so the entire expression becomes 9.48 x 1010.
What is a real number in computing?
The so-called "real numbers" are simply numbers that permit decimals. Think of them as numbers in scientific notation, which allow very big or very small exponents (somewhere in the range of -300 to +300), and about 15 significant digits. Since their precision is not unlimited, they do not exactly correspond to what is called "real numbers" in mathematics.
Why do you have exponetial notation?
Exponential notation is used to write really big numbers in smaller forms. Without this, extremely large numbers could not easily be used on a regular medium such as paper. For example, the mass of the earth is about 5.98 x 1024 kilograms. Without scientific notation (which uses exponents of course), that number would require 25 characters to write out, instead of the nine characters used here. Another reason that exponents are so useful is the fact that they allow us to group data together, making it simpler to work with. Take this equation for example: a × a × 1/a × 3/a × 7a × 2a = 7 With all of those "a" terms being separate, there is no simple way to solve that equation. With exponents on the other hand, we can group those terms together and say: ∴ 42a4 / a2 = 7 ∴ 42a2 = 7 ∴ a2 = 7/42 ∴ a = (1/6)1/2 ∴ a = 61/2 / 6 ≈ 0.40825
Are allow and prohibit synonyms or antonyms?
They are antonyms. Allow is often the opposite of prohibit.
Why do non-believers in God always judge me and think I've lost it?
It is rare for atheists to criticise believers in any way, rather to have their own views and allow you to have yours. The fact that you feel that some nonbelievers have judged you suggests that this is of your own doing. Ask yourself whether you have sought to convince others of the truth of your beliefs, or have even tried belligerently to proselytise. If so, they are merely responding to unwanted behaviour on your part. The answer is to simply be a Christian, but also allow others to believe as they wish. Answer a question about your faith briefly, if directly asked, but otherwise keep your faith as a personal and family thing. You will soon find that nonbelievers respect your faith and no longer criticise you for it.
