(-12)+(-13)+36+(-11)=-(11+12+13)+36=-36+36=0
tick mk nha các bạn
(-12) + (-13) + 36 + (-11)
= -(11 + 12 + 13) + 36
= -36 + 36
= 0
(-12) + ( -13 ) + 36 + (-11)
Tính nhanh
( - 12 ) + ( - 13 ) + 36 + ( - 11 )
Tính hợp lí:
(-12)+(-13)+36+(-11)
\(a,\dfrac{-6}{11}:\left(\dfrac{3}{5}:\dfrac{4}{11}\right)\) b,\(\dfrac{7}{12}+\dfrac{5}{12}:6-\dfrac{11}{36}\)
\(c,\left(\dfrac{4}{5}+\dfrac{1}{2}\right):\left(\dfrac{3}{13}-\dfrac{8}{13}\right)\) \(d,\left(\dfrac{2}{3}-\dfrac{1}{4}+\dfrac{5}{11}\right):\left(\dfrac{5}{12}-1-\dfrac{7}{11}\right)\)
Giúp mik nha:>>
