a) 4524-(864-999)-(36+3999) = 4524-(-135)-4035 = 4659-4035 = 624

b) 1000-(137+572)+(263-291) = 1000-709+(-28) = 291+(-28) = 263

c) -329+(15-101)-(25-440) = (-329)+(-86)-(-415) = (-415)-(-415) = 0

Answer 2

a, 4524 - (864 -999) - (36 + 3999)

= 4524 - (864 - 999) - 36 + 3999)

= 4524 - -4170

= 8694

b,1000 - (137 + 572) + (263 - 291)

= 1000 - (137 + 572) + 263 -291)

= 1000 - 681

= 319

c, -329 + (15 - 101) - (25 - 440)

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

= -329 + -551

= -880

Mình phá ngoặc ra đấy.

Answer 4

a) 4524-864+999-36-3999

=4524-(864+36)+(999-3999)

=4524-900-3000

=624

b)1000-(137+572)+(263-291)

=1000-(137+572+291)+263

=1000-1000+263

=263

c)-329+(15-101)-(25-440)

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

=-430-10+440

=0

Answer 5

a) 4524 - (864 -999) - (36 + 3999)

= 4524 - (864 - 999) - 36 + 3999)

= 4524 - -4170

= 8694

b)1000 - (137 + 572) + (263 - 291)

= 1000 - (137 + 572) + 263 -291)

= 1000 - 681

= 319

c) -329 + (15 - 101) - (25 - 440)

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

= -329 + -551

= -880
