Efectuati:
a)1320+[48x23+(340x11-60x5)-235x7]=?
b)2307+{3702+[270:3+3x(280x5-3x230)]}=?
c)31975+200 x[8x(1270-2x350)+2340:5]=?

Answer 1

a)1320+[1104+(3740-300)-1645]=1320+[1104+3440-1645]=1320+2899=4219
b)2307+{3702+[90+3X(1400-690)]}=2307+{3702+[90+3X710]}=2307+{3702+2220}=2307+5922=8229

Answer 2

a) 1320+[48x23+(340x11-60x5)-235x7]=
1320+[1104+(3740-300)-1645]=
1320+(1104+3440-1645)=
1320+289=
4219

b)2307+{3702+[270:3+3x(280x5-3x230)]}=
2307+{3702+[90+3x(1400-690)]}=
2307+[3702+(90+3x710)]=
2307+[3702+(90+2130)]=
2307+(3702+2220)=
2307+5922=
8229

c)31975+200 x[8x(1270-2x350)+2340:5]=
31975+200x[8x(1270-700)+468]=
31974+200x(8x570+468)=
31974+200x(4560+468)=
31974+200x5028=
31974+1005600=
