155

Tik cho mk nha........cảm ơn rất nhiều

= 333 + 122 -200 -100

= 455 - (200+100) 

= 455 - 300

= 155

\(\left(-8\right)+\left(-7\right)+\left(-10\right)\)

\(=-8-7-10\)

\(=-15-10=-25\)

\(\left(-229\right)+219-401+12\)

\(=\left(219-229\right)-401+12\)

\(=-10-401+12\)

\(=-399\)

\(555-\left(-333\right)-100-80\)

\(=555+333-100-80\)

\(=888-100-80\)

\(=780-80=700\)

\(300-\left(-200\right)-\left(-120\right)+18\)

\(=300+200+120+18\)

\(=500+120+18\)

\(=620+18\)

\(=638\)

a) = (-15)+(-10)

= -25

b) = (-222)-100-80

= (-322)-80

= -402

c) = 229+219-401+12

= 448-401+12

=47+12

= 59

d) = 500-(-120)+18

= 620+18

= 638

A,-25

B,-402

C,59

D,638

555-(-333)-100-80=708

-(-229)+(-229)-401+12=-389

-(-200)+(-120)+18=98

1)708

2)-389

3)98

\(a.\left[\left(-8\right)+\left(-7\right)\right]+\left(-10\right)=\left(-15\right)+\left(-10\right)=-25\)

\(b.555-\left(-333\right)-100-80=\left(555+333\right)-\left(100+80\right)=888-180=708\)

\(c.-\left(-229\right)+\left(-219\right)-401+12=\left(229-219\right)-\left(401-12\right)=10-389=-379\)

\(d.300-\left(-200\right)-\left(-120\right)+1=\left(300+200\right)+\left(120+1\right)=500+121=621\)

A. -25

B. 708

C. -379

D. 638

Mình chỉ ghi kết quả thôi ! Bạn biết cách tính chứ!

A) = -15 +(-10)=-25

B) 708

c)-309

d) 638

a: \(A=\left[111\cdot\left(38\cdot3-133\right)\right]\cdot2018\)

\(=111\cdot\left(-19\right)\cdot2018=-4255962\)

b: \(B=\left[25\left(1+3\cdot3-5\cdot2\right)\right]:20182019\)

\(=25\left(1+9-10\right):20182019=0\)

c: \(C=\dfrac{\left[244\left(395-195\right)\right]}{122\cdot200}=\dfrac{244}{122}=2\)

d: \(D=\dfrac{355\cdot45\cdot55}{11\cdot9\cdot7}=\dfrac{355\cdot5\cdot5}{7}=\dfrac{8875}{7}\)
