Calculati a : 4 + b x 2 +10 x c stiind ca : a= 183 - (172 +160 ) : 4+ 25 x (5x3 - 15) b= 25+3 x [21 - (7-7) : 2]; 9 c= [(20+4 ) ; 6-4 ] x35 +2 x(5x15-2x3x5) .. se poate putin ajutor , va rog!

a: 4 + b x 2 +10 x c
a= 183 - (172 +160 ) : 4+ 25 x (5x3 - 15) =
=183 - 332 : 4+ 25 x (15 - 15) =
=183 - 83+ 25 x 0 =
=100

b= 25+3 x [21 - (7-7) : 2]: 9 =
=25+3 x (21 - 0: 2): 9 =
=25+3 x 21: 9 =
=25+63: 9 =
=25+7 =
=32

c= [(20+4 ) : 6-4 ] x35 +2x(5x15-2x3x5)=
= (24 : 6-4) x35 +2x(75-30)=
= (4-4) x35 +2x40=
= 0+80=
=80

a: 4 + b x 2 +10 x c =
=100: 4 + 32 x 2 +10 x 80 =
=25+64+800=
=889
a=183- (172+160):4+25(5×3-15)=183-332:4+25(15-15)=183-83+25×0=100+0=100

b=25+3×[21-(7-7):2]:9=25+3(21-0:2):9=25+3×21:9=25+63:9=25+7=32

c=[(20+4):6-4]×35+2(5×15-2×3×5)=(24:6-4)×35+2(75-30)=(4-4)×35+2×35=0×35+70=70

a:4+b×2+10×c=100:4+32×2+10×70=25+64+700=789
