Let me break it down for you in a few steps:
1+1=2
2+2=4
3+3=6
4+4=8
2 4 6 8
Since there are no arithmetic symbols separating each of these addition math exercises, you are likely going to be multiplying each of their sums by each other inside parentheses as follows:
(1+1) (2+2) (3+3) (4+4) = 2 x 4 x 6 x 8
2x4 = 8
8x6=48
48x8=384
Therefore your final answer to this equation is 384.
