1 ) (12 x19) + 3 x  24 x4 - 6 x 33 x 2

2 ) 35 x1001  -35

Answer 1

1) 12 x 19 + (3 x 4) x 24 - (6 x 2) x 33

   = 12 x19 + 12 x 24 -12 x 33

   = 12 x (19 + 24 - 33)

   = 12 x 10

   =120

2) 35 x1001-35

   =35 x (1001 - 1)

   = 35 x 1000 

   = 35 000

Answer 2

1) 12 x 19 + (3 x 4) x 24 - (6 x 2) x 33

   = 12 x19 + 12 x 24 -12 x 33

   = 12 x (19 + 24 - 33)

   = 12 x 10

   =120

2) 35 x1001-35

   =35 x (1001 - 1)

   = 35 x 1000 

   = 35 000

Answer 3

1) 12 x 19 + (3 x 4) x 24 - (6 x 2) x 33

   = 12 x19 + 12 x 24 -12 x 33

   = 12 x (19 + 24 - 33)

   = 12 x 10

   =120

2) 35 x1001-35

   =35 x (1001 - 1)

   = 35 x 1000 

   = 35 000

Answer 4

1) 12 x 19 + (3 x 4) x 24 - (6 x 2) x 33

   = 12 x19 + 12 x 24 -12 x 33

   = 12 x (19 + 24 - 33)

   = 12 x 10

   =120

2) 35 x1001-35

   =35 x (1001 - 1)

   = 35 x 1000 

   = 35 000

Answer 5

1) 12 x 19 + (3 x 4) x 24 - (6 x 2) x 33

= 12 x19 + 12 x 24 -12 x 33

= 12 x (19 + 24 - 33)

= 12 x 10

=120

2) 35 x1001-35

=35 x (1001 - 1)

= 35 x 1000 

= 35 000

Answer 6

1 = 120
