Answer 3

Let's calculate the given expressions:

А) -8 + (-4) - 15 + 6

= -8 - 4 - 15 + 6 (Since adding a negative number is the same as subtracting it) = -12 - 15 + 6 (Combine like terms) = -27 + 6 (Combine like terms) = -21 (Final result)

Б) 6 - (-7) - 3 - 9

= 6 + 7 - 3 - 9 (Since subtracting a negative number is the same as adding it) = 13 - 3 - 9 (Combine like terms) = 10 - 9 (Combine like terms) = 1 (Final result)

В) -4 * 7 - 30 * (-1)

= -28 - (-30) (Multiplying a number by -1 is the same as changing its sign) = -28 + 30 (Adding a negative number is the same as subtracting its absolute value) = 2 (Final result)

г) -15 : (-3) 0 : (-5)

Note: Division by zero is undefined, so the expression "0 : (-5)" is not valid.

Please double-check your last expression, as the division by zero is not allowed in arithmetic. If you meant a different expression, feel free to ask, and I'll be glad to help you with it.
