پاسخ

$$
10 - (-4) = 10 + 4 = 14 \\[2ex]
-10 - (-5) = -10 + 5 = -5 \\[2ex]
-10 - (+20) = -10 + (-20) = -30 \\[2ex]
-8 -4 = -8 + (-4) = -12 \\[2ex]
-10 - (+5) = -10 + (-5) = -15\\[2ex]
10 - (+5) = 10 + (-5) = 5\\[2ex]
-16 + 15 = -1\\[2ex]
10 - 6 = 4 \\[2ex]
10 - (-5) =10 + (+5) = 15 \\[2ex]
-14 + 20 = 6\\[2ex]
10 - 20 = 10 + (-20) = -10\\[2ex]
-10 - (-20) = -10 + 20 = 10
