Answer 2

Let's solve the given arithmetic expressions one by one:

(1) -7 - 10 = -17 (2) -17 + 29 = 12 (3) -12 + 9 = -3 (4) -46.5 + 48.7 = 2.2 (5) 12 + (-8) = 4 (6) 3.45 + (-1.95) = 1.5 (7) 3 + (-11) = -8 (8) 9.07 + (-5.9) = 3.17

Here are the results of each expression: (1) -7 - 10 = -17 (2) -17 + 29 = 12 (3) -12 + 9 = -3 (4) -46.5 + 48.7 = 2.2 (5) 12 + (-8) = 4 (6) 3.45 + (-1.95) = 1.5 (7) 3 + (-11) = -8 (8) 9.07 + (-5.9) = 3.17
