-45 plus 512 plus 45 plus 56 = 568
77 plus 76 plus 69 plus 56 is equal to 278.
2w2 + 22w + 7 = 0 w = [-22 +/- sqrt(22*22 - 4*2*7)] / (2*2) = [-22 +/- sqrt(484 - 56)] / 4 = [-22 +/- sqrt(428)] / 4 so w = -0.328 or w = -10.672
1 + 65 + 56 = 122
1000 + 56 + 63 = 1,119
56 + 4 + 951546 = 951606
12 + 56 + 92 = 160
107+(-82)+56 = 81
