107 + 108 + 109 = 324... Not sure if you meant consecutive* as in 1-2-3-4 or 1.1-1.2-1.3 you can also do 107.6 + 107.7 + 107.8 and get 323.1

( 323 )4 = (3 sixteens) + (2 fours) + (3 ones) = ( 59 )10

The numbers are: -5 and 3
The two numbers that add to make 3 and multiply to make -40 are 8 and -5. This is because 8 + (-5) = 3 and 8 × (-5) = -40.
How about the prime numbers of: 3+7 = 10
