Answer 1

Orice numar care se afla in modul devine numar pozitiv

exmplu |-5 | = 5

|5 | = 5

|-3+5| = |2 | =2

1) 5-2+3-1 = 3+3-1 = 5

2) 2-5+8-|2| = -3+8 -2 = 5-2 = 3

3) |5-8| -|5-4| - |9-1| + |13-16| = |-3| -|1|  - |8| + |-3| = 3-1-8+3 = 6-9 = -3

4) 7+|8-9|-|27-25|  = 7+1-2 = 8-2 = 6

5) -8-12+|-36+25| -|-7+8| = -20 +11-1 = -9-1 = -10

6) 8-5-|16-25| +6 = 3-9+6 = -6+6 = 0
