"Real number" means all the numbers we know, including positive and negative numbers.
The only numbers that are not included are "imaginary numbers" - numbers that have an imaginary part i (used only i physics or high mathematics).

What kinds of numbers would I multiply by to get answers that are slightly less than my starting number A lot less?
NO for Integers NO for Real Numbers proof 1 * any integer is not bigger than that integer nor is 0 * any integer. proof for Real Numbers is easier any real < 1 * any real > 0 is not larger than the second Real for example .5 * 1 = .5 is less than 1 or .5 * 2 = 1 less than 2 or .5 * = 1 less than 2 or -1 *3 = -3 less than 3 so all fractions times a positive Real is less than that positive Real All negative numbers times a positive Real is less than that positive Real and 0 or 1 times all positive Reals is also less than that positive Real NO NO NO is the answer
What numbers are greater than -1 and less than -1?
0
The only number that is one less than a square?
Every non-negative real number is a square (every number if in the complex field) so every real number greater than or equal to -1 is one less than a square. Even if you restrict yourself to perfect squares, of the form n2, then n2 - 1 = (n-1)*(n+1) is one less than a square. There are infinitely many such numbers.
When is the reciprocal of a number greater than the number?
When the number is between 0 and 1, or less than -1
What is a number less than 1?
A number less than 1 is any real number that falls between 0 and 1 on the number line. This includes fractions, decimals, and percentages such as 0.5, 0.25, 0.75, and 0.001. These numbers are considered to be proper fractions or proper decimals because they are smaller than 1 but greater than 0.
