Solve the following integer arithmetic problems.

Решение:

1. \( 3 + (-3) \)

\( 3 + (-3) = 3 - 3 = 0 \)

1. \( 4 + (-23) \)

\( 4 + (-23) = 4 - 23 = -19 \)

1. \( -11 - (-17) \)

\( -11 - (-17) = -11 + 17 = 6 \)

1. \( -10 + 2 \)

\( -10 + 2 = -8 \)

1. \( -30 - (-24) \)

\( -30 - (-24) = -30 + 24 = -6 \)

1. \( -7 + 23 \)

\( -7 + 23 = 16 \)

1. \( 20 \)

\( 20 \)

Ответ: 0, -19, 6, -8, -6, 16, 20.
