 dau 32 de puncte !!!!!!!!! va rog ajutima la matematica am nevoie urgenttt va rogggg !!!!!!!!!!!!!! 32 de puncte + coroana !!!!!!!!!!!!
efectuati tinand cont de ordinea operatiilor si de semnificatia [parantezelor
a . (-2)+(-5)x4 ; b. (-5)x(-8) -4 x 10 ; c 4-4:4 ; d. (-3)+(-9):(-3) ; f. -10x{100-[100-(100-1)]}
g. -5[-4+(-6+2-0)x(-3)-(11-7)x2]-(-4)x(-1) ; e.-5+(-4+6)(-2)-(-8)x0+(-11+6+8)x(-100) ajutatimaaaaaaaaaaaaa !!!!!!!!!!!!!!!

Answer 1

a . (-2)+(-5)x4 =-2-20=-22
b. (-5)x(-8) -4 x 10 =-40-40=-80
c. 4-4:4 =4-1=3
d. (-3)+(-9):(-3) =-3+3=0
f. -10x{100-[100-(100-1)]} =
=-10x[100-(100-99)] =
=-10x(100-1) =
=-10x99 =
=-990
g. -5[-4+(-6+2-0)x(-3)-(11-7)x2]-(-4)x(-1) =
=-5[-4+(-4)x(-3)-4x2]-4 =
=-5(-4+12-8)-4 =
=-5[0]-4 = 0-4=-4

e.-5+(-4+6)(-2)-(-8)x0+(-11+6+8)x(-100) =
=-5+(2)(-2)-0+(3)x(-100)=
=-5-4-300=
=-309
