TL:
435 x 85 + 435 x 45 - 435 x 31 + 435
= 435 x 85 + 435 x 45 - 435 x 31 + 435 x 1
= 435 x (85 + 45 - 31 + 1)
= 435 x 100

Tính nhanh.
a) 2459 - (400 + 459)
b) 435 nhân 25 + 76 nhân 435 - 435
c) 36 nhân 49 + 51 nhân 36
a) 2459 - ( 400 + 459 )
= 2459 - 400 - 459
= 2000 - 400
= 1600
b) 435 x 25 +76 x 435 - 435
= 435 x 25 + 76 x 435 - 435 x 1
= 435 ( 25 + 76 - 1 )
= 435 x 100
= 43500
c) 36 x 49 + 51 x 36
= 36 ( 49 + 51 )
= 36 x 100
= 3600

a) 2459 - ( 400 + 459 )
= 2459 - 400 - 459

Cái * là nhân
b) 435 * 25 +76 * 435 - 435

= 435 * 100
= 43500 (L~I~K~E)
c) 36 * 49 + 51 * 36
= 36 * ( 49 + 51 )
= 36 * 100
