Question

aflaţi dacă e adevarat sau fals
5-3=3-5
(11-3)-8=11-(3-8)
(11-3)8=11-3-8
11-(-3)-8=11-(-3-8)

Answer 1

5-3=3-5 <=>2=-2 fals
(11-3)-8=11-(3-8) <=>8-8=11-(-5) <=>0=16 fals
(11-3)8=11-3-8 <=>8-8=8-8 <=>0=0 adevarat
11-(-3)-8=11-(-3-8) <=>14-8=11-(-11) <=>6=22 fals

Answer 2

5-3=2
3-5=-2
5-3=3-5 FALS

(11-3)-8
=8-8=
=0
11-(3-8)=
=11-(-5)=
=11+5=
=16 
(11-3)-8=11-(3-8) FALS

(11-3)8=
=8 ori 8=
=64
11-3-8=
=8-8=
=0
(11-3)8=11-3-8 FALS

11-(-3)-8=
=11+3-8=
=14-8=
=6
11-(-3-8)=
=11+3-8=
=14-8=
=6
11-(-3)-8=11-(-3-8) ADEVĂRAT
