Question

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

Answer 1

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 AAAAAAAAA
if you do think it's a prime number, go to BBBBBBB

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

BBBBBBBBBBB
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

Answer 2

A=10

b= 2+ 3+5+7
= 17

a × b

=17×10
=170
