Answer:
202
Explanation:
Because we are adding prime numbers.
Our prime numbers are 31, 83, 71 and 17 Because prime numbers are numbers that don't have 1 factor regarding 1 so nothing can go into 31,81,71 or 17.
45 does have a factor and that is 9 and 5.
56 has 9 x 5 28 x 2 14 x 4
So like I said we will now add 31,83,71 and 17
SO 83 + 17=100
100 + 31=131 131 + 71=202 and there is all your answers.
Hope this helps have a awsome day:)
