Rezolvați exercițiul 3 urgent.. Am nevoie

Answer 1

a) -8 : (-4) -4*(-14)=
=2+56
=58

b)-2 * 10*(-12)-18:(-6)
= -240+3
= - 237

c) -7*(-5)-2(3*6-5)=
= 35-2*(18-5)=
= 35- 2*13
= 35-26
= 9

d) -6+ [( 10800-768) :2 +192 ] :(-6)=
= -6+ (10032 :2 +192) : (-6)=
= -6+ (5016+192):(-6)=
= -6 + 5208 : (-6)=
= -6+868
=862

e)  15- ( 300-1100) : (-10)=
= 15 - (-800) : (-10)
= 15+800: (-10)=
= 15 -80
= -65

f) 8240 : (124 -18*2 -48 ) =
= 8240 : (124-36-48)
= 8240 : 40 
= 206

g) 3725- ( 5003- 2*889)=
= 3725- ( 5003-1778)=
= 3725- 3225
= 500

h) ( 100- 4*161) :4-85=
= (100-644):4-85=
=-544:4-85=
= -136-85=
= -221 

i)  -7* [-5+2*1*(-5)-6:(-2)]
= -7 * (-5-10+3)=
= -7*(-12)
= 84

j) 91-{5*[-5-2*8*(-3)]-2*[(-2)*(-1)-(-2)*(-7)]}=
= 91- [ 5*(-5+48)-2*(2-14)]
=91- (5* 43-2*(-12)
=91- ( 215+24)=
= 91-239
= - 148

k) [(-5+6)*(-3)+5]:2=
= (-3+5):2
= 2:2
=1
