The number 20 is significant in various contexts, such as representing the age of adulthood in many cultures and the completion of a score, a term historically used for twenty items, particularly in counting livestock. In mathematics, it is the first tetrahedral number, relating to triangular numbers. Additionally, in sports, particularly in cricket, a Twenty20 format has gained popularity for its fast-paced, short-duration matches.
400 is a significant number because it is a square number as 20*20 = 400
When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits. 310 × 20 = 6200 6200 already has two significant digits.
The number 20 can be expressed in significant figures depending on how precise you want it to be. If it is written as "20," it has one significant figure. If you want to indicate that both digits are significant, you can write it as "20." or "2.0 x 10^1," which shows two significant figures. The use of a decimal point or scientific notation clarifies the number of significant figures intended.
Yes 2.0 is the same as 2 which is a whole number or an integer
The number of permutations of 20 things taken 20 at a time is 20 factorial or 2,432,902,008,176,640,000.
20 is the number associated with a 'score.'

Significant digits refer to the number of digits that are known versus the number of digits that are estimated. So if the number 20 is an approximation, there is only one significant digit, which is the 2. However, if 20 is accurate to the ones place, then there are 2 significant digits. 20.00 has four significant digits, because it is known that the number is accurate down to the hundredths place.
Well... you can use it for a number of things.

Not quite. Number of combinations is 20, number of permutations is 10. Any 2 from 5 is 10 but in any order doubles this.
Potassium has a gram atomic mass of 39.1, to three significant digits (one more significant digit than "20 meq" has). Therefore, one meq = 39.1 mg, and 20 meq = 20(39.1) = 7.8 X 102 mg, to the justified number of significant digits.
When the number 20 is announced in "The Giver," it is the age at which individuals in the community are assigned their lifelong jobs. This assignment is a significant event in the novel, as it determines the course of their future and how they will contribute to society.
