54 x 133 x 45 x 133 + 133
= ( 54 + 45 + 1 ) x 133
= 100 x 133
= 13300
54 x 133 + 45 x 133 + 133
= 133 x ( 45 + 54 + 1 )
= 133 x 100
= 13300

1/ Tìm y
a) y x 42 = 4200
y = 4200 : 42
y = 100
b) y : 42 = 200
y = 200 x 42
y = 8400
2/ Tính nhanh
a) 21 x 34 + 21 x 16
= 21 x ( 34 + 16 )
= 21 x 50
= 1050
b) 34 x 56 + 56 x 36
= 56 x ( 34 + 36 )
= 56 x 70
= 3920

Tính nhanh:
a) 56 x 44 + 56 x 11 + 56 x 45
= 56 x ( 44 + 11 + 45 )
= 56 x 100
= 5600
b) 8 x 3 + 8 x 6 + 8
= 8 x ( 3 + 6 + 1 )
= 8 x 10
= 80
