Facem inmultirile intai:

472+524x3-223x7= 472 + 1572 - 1561 =  2044 - 1561 =  483  

Interiorul parantezei intai:

2x( 55+432x44-55)=  2 x (55 + 19008 - 55)  = 2 x 19008 = 38016

B) 472+524x3-223x7
472+1572-1561
2044-1561=483

a) 2x(55+432x44-55)
2x(55+19008-55)
2x(19063-55)
2x19008=38016
CRED CA ASA ESTE CORECT DACA NU INSEAMNA CA AM GRESIT CEVA!!
