Question

Calculați valoarea absoluta a numerelor :
a=1+3-5+7-9+11
b=-5-[-8+(-4)]-(-7).

Answer 1

a=1+3-5+7-9+11=
a=2-5+7-9+11=
a=-3+7-9+11=
a=4-9+11=
a=-5+11=
a=6

b=-5-[-8+(-4)]-(-7)=
b=-5-(-8-4)+7=
b=-5-(-12)+7=
b=-5+12+7=
b=7+7=
b=14

Answer 2

a =2-5+7-9+11 a=-3+7-9+11 ,a=4-9+11 ;a=-5+11;a=6.b)-5 (-8-4)-(7);b=-5-(-12)-(-7),b=-5+12+7b=7+7b=14
