-0.5

Answer 2

Let's solve the arithmetic expressions one by one:

a) 3 + 10 = 13 b) 0 - 11 = -11 c) –1.(-7) = -(-7) = 7 (Here, -1 multiplied by -7 gives us a positive 7) d) 0:(-3) = 0 (Division by any non-zero number will result in 0) e) 8 + (-16) = -8 f) 14 - (-2) = 14 + 2 = 16 g) 2 - (-11) = 2 + 11 = 13 h) -28 : (-7) = 4 (When dividing two negative numbers, the result is positive) i) -3 + (-9) = -12 j) –5 - 4 = -9 k) -4.4 = -4.4 (This is already a decimal number) l) –15:30 = -0.5 (Dividing -15 by 30 gives us -0.5)

Remember, when you see two consecutive negatives (e.g., -a or -(-b)), the double negatives cancel each other out, resulting in a positive value.
