1-2-(+8): B-5-(-2), C-(-3) -(-5); D-11-(-2):
F=(-7)-(-4); G=1-(+10); H-3-0. 1-0-(-3):
E-(-2) - (+5):
J-0-(+3)
VĂ ROG DAU COROANĂ ​

Answer 1

•1-2-(+8) =1-16=-15

•B-5-(-2)= b+5×2=b+10

•C-(-3) -(-5)=c+3-(-5)=c+3+5=c +8

•D-11-(-2)=d-11+2=d-9

•F=(-7)-(-4)

f=-7-(-4)

f=-7+4

f=-3

•G=1-(+10)

g=-(10-1)

g=-9

•H-3-0.1-0-(-3) = h-3-0.1-(-3)=h-3-0.1+3=h-0.1

•E-(-2) - (+5)=e+2-5=e-3

e-3 - formular alternativ ≈ -0.281718

•J-0-(+3)=j-3
