what are two prime numbers that if added together equal 23?
22+1
To find two prime numbers that add up to 23, let's start by listing the prime numbers up to 23:
2, 3, 5, 7, 11, 13, 17, 19, 23
Now let's check if any pair of these prime numbers adds up to 23:
2 + 3 = 5
2 + 5 = 7
2 + 7 = 9 (not equal to 23)
...
17 + 19 = 36 (not equal to 23)
19 + 23 = 42 (not equal to 23)
None of the pairs from this list adds up to 23, so we can conclude that there are no prime numbers that satisfy this condition.
To find two prime numbers that, when added together, equal 23, we can start by checking prime numbers less than 23.
First, let's list the prime numbers less than 23:
2, 3, 5, 7, 11, 13, 17, 19
To check if any combination of these prime numbers adds up to 23, we can start by adding the largest prime number (19) to the smallest prime number (2).
19 + 2 = 21 (not equal to 23)
We continue checking other combinations:
17 + 2 = 19 (not equal to 23)
13 + 2 = 15 (not equal to 23)
11 + 2 = 13 (not equal to 23)
7 + 2 = 9 (not equal to 23)
5 + 2 = 7 (not equal to 23)
3 + 2 = 5 (not equal to 23)
Unfortunately, after checking all possible combinations of prime numbers less than 23, we don't find any pair that adds up to 23. This means that there are no two prime numbers that satisfy the given condition.
the best approach to solve this is find out the combinition that will make 23 e.g.
1+22, 2+21, 3+20,4+19, 5+18, 6+17, 7+16, 8+15, 9+14,10+13, 11+12. Then it repeats. Now lets evaluate which pair is prime. (Prime is a number which is divisible by 1 and by itself). SO there is notwoprime numbers which will add up to make a sum of 23.
