[ 71- (-59)] - [ (-83)- (95)]

=130-(-179)

=308

ngta bảo tính nhanh chứ không phải tính chậm mẹ

[(-59)+71]-[-83-(-95)

=12-12

=0

[(-59) + 71] - [-83 -(-95)]

= 12 - 12

=0

a, -323 + [(-874) + 564 - 214]

= -323 - 874 + 564 - 214

= - (323 + 874) + (564 - 214)

= - 1197+ 350
= - 847

b, [ 71 + (-59) - (-83 - (95)]

= 71 - 59 + 83 + 95

= 12 + 178

= 190 

Giúp em với ạ🥲🥹

a: \(\left[\left(-59\right)+71\right]-\left[\left(-83\right)-\left(-95\right)\right]\)

\(=\left[71-59\right]-\left[-83+95\right]\)
=12-12

=0

b: \(\left(435-167-89\right)-\left(435-89\right)\)

\(=435-167-89-435+89\)

\(=\left(435-435\right)+\left(89-89\right)-167\)

=0+0-167

=-167

c: \(\left(-624\right)-\left[\left(376+245\right)-45\right]\)

\(=\left(-624\right)-\left[376+245-45\right]\)

\(=\left(-624\right)-376-200\)

=-1000-200

=-1200

a,

a)(461+(-78)+40)+(-416)=7

b,

b)((-59)+71)-(-83-(-95))=0

tick mình nah mọi ngừoi

a,[461+(-78)+40]+(-401)

=461+(-78)+40+(-401)

=[461+(-401)+40]+(-78)

=100                   +(-78)

=22

a: \(-59+71-\left\{-83-\left(95\right)\right\}\)

\(=71-59+81+95\)

\(=12+81+95\)

\(=93+95=188\)

b: \(-257-\left\{\left(-257+156\right)-56\right\}\)

\(=-257-\left(-257+156-56\right)\)

\(=-257-\left(-257+100\right)\)

\(=-257+257-100=-100\)

c: Sửa đề:\(\left(435-167\right)-89-\left(435-89\right)\)

\(=435-167-89-435+89\)

=\(\left(435-435\right)+\left(-89+89\right)-167\)

=0+0-167

=-167

d: \(-329+\left(15-101\right)-\left(25-440\right)\)

\(=-329+15-101-25+440\)

\(=\left(440-329-101\right)+\left(15-25\right)\)

=10-10

=0

e: \(\left(116+124\right)+\left(215-116-124\right)\)

\(=116+124+215-116-124\)

\(=\left(116-116\right)+\left(124-124\right)+215\)

=0+0+215

=215

f: \(4524-\left(864-999\right)-\left(36-999\right)\)

\(=4524-864+999-36+999\)

\(=4524-\left(864+36\right)+999\cdot2\)

\(=4524-900+1998=5622\)

a) -38

b) 188

sai thì thôi

a) [461 + (-78) + 40] + (-461)

= 461 + (-78) + 40 + (-461)

= [461 + (-461)] + (-78) + 40

= -38

b) [(-59) + 71] - (-83) - (-95)

= (-59) + 71 + 83 + 95

= 190
