Answer 1

Răspuns:

a) - 25 + |-12| + |-8| + (-10)

= -25 + 12 + 8 + 10

= -25 + 30

= 5

b) +17 + |+6| + |-15| + (-20) =

17 + 6 + 15 - 20 =

= 23 + 15 - 20

= 38 - 20

= 18

c) -4 + |+6+(-11)| + |-15+12| + (-18)

= -4 + 6 + 11 + 15+12 -18 =

=13 + 27 - 18

= 13 + 9

= 22

d) | 1 +(-9) |+ |3+ (-15) + 6| + (-8) |

= 1 + 9 + 3 + 15 + 6 + 8

= 10 + 18 + 8

= 10 + 26

= 36

e) | + 26 + (-15) + (-14) | + | - 21 + 12 |

= +25 + 15 + 14 + 21 + 12

= 50 + 14 + 33

= 83 + 14

= 97

f) -7 + | - 12 + 12 | + | -7 | + (+14)=

= -7 + 12 + 12 + 7 + 14

=5 + 12 + 7 + 14

= 17 + 7 + 14

= 24 + 14

= 38
