Let * operate as follows: for any a + B ≥ 10, Let * operate as follows: for any a + B ≥ 10, then a * b = a + B; if a + B < 10, then a * b = ab. then (1 * 2) + (2 * 3) + (3 * 4) + (4 * 5) + (5 * 6) + (6 * 7) + (7 * 8) + (8 * 9) + (9 * 10) = ()

1*2=1x2=2
2*3=2x3=6
3*4=3x4=12
4*5=4x5=20
5*6=5+6=11
6*7=6+7=13
7*8=7+8=15
8*9=8+9=17
9*10=9+10=19
So the original formula = 2 + 6 + 12 + 20 + 11 + 13 + 15 + 17 + 19 = 115
