There are many different combinations. One example is two and 31.
I am not sure if any two consecutive numbers can add up to an even number.
1-5
All of your double numbers such as 33 and 77 occur within the first hundred numbers. Viz 11, 22, 33, up to 99. That is 9 double numbers.
2 and 17
No, even numbers are evenly divisible by two, which means that only the multiples of two are even numbers. Odd numbers make up the other integers. There is no such thing as an odd or even decimal.
33+30+36=99
33
169
95
33 and 14
For two primes to add up to an odd number, one of them has to be two. 33 isn't prime, so there is no solution.
I am not sure if any two consecutive numbers can add up to an even number.
There are no two prime numbers in which a product of 100 is possible.
19 and 1
A one and two zeros
They are 31, 32, 33 and 34.The numbers are 31, 32, 33 and 34.
These two sets together make up the set of real numbers.
