Salut! =)
a × b = b × a ( PROPRIETATE A INMULTIRII )
a ) a = 24
b = 13
---------------
a × b = 24 × 13 = 312
b ) a = 104
b = -5
-------------
a × b = 104 × ( - 5 ) = -520
c ) a = -11
b = -13
--------------
a × b = -11 × (-13 ) = 143
d ) a = 0
b = -2020
----------
a × b = 0 × ( -2020) = 0
e ) a = -19
b = 0
-------------
a × b = -19 × 0 = 0
f ) a = -2
b = +31
--------
a × b = -2 × 31 = -62
Bafta! =)
