Ais the smallest two digit whole number; "b" is the sum of prime numbers up to 10. what is a b?

Whole numbers are like 0,1,2,3,4,5...
the smallest one is 10

prime numbers
I do not accept 1 as a prime number, if you agree, go to
if you do think it's a prime number, go to


2,3,5,7
2+3+5+7=17
a+b=10+17=27


1,2,3,5,7
1+2+3+5+7=18
a+b=10+18=28

if  you do not think a is a prime number, then the answer is 27
if you do think 1 is prime number then the answer is 28
