Yes, I did.
Una hora y veinte minutos
These are the prime numbers 1-20 2,3,5,7,11,13,17,19
The numbers 1-20 are on a dart board so there are twenty numbers.
20 and 1. 20 + 1 = 21 20 - 1 = 19
The sum of the numbers from 1 to 20 inclusive is 220.
2/5 of the numbers from 1 to 20 are prime numbers
The square numbers between 1 and 20 are 1,4,9 and 16.
The counting numbers from 1 to 20 are called natural numbers. There are larger sets that include the numbers from 1 to 20, but have other members as well. For example, the integers contain 1 through 20, but also all numbers 21, 22, 23, ... The set of real numbers includes all numbers on the number line, which includes 0 and negative numbers and irrational numbers like pi, but also includes 1 through 20. Etc.
Say you have 5 and 1/10 and you have to add 6 and 3/20, you add the whole numbers, (11) and then convert the 10 of 1/10 to 20 (20/10 is 2), then you have to multiply the 1 by 2 to get 2/20 (equivalent fraction of 1/10). Now you can add the fractions, i.e. 4/20 (or simplified, 1/5). Final answer is 11 and 1/5
20 There can be two answers to this: I'll assume this is what you meant-> let's say you mean like pairing the numbers 1-5 with the numbers 6-9. 5*4=20
The numbers are: -1 and -20
