1. 41 x (46 - 24) = (41x 46) - (41 x 24) = 1886 - 984 = 902 2. (28 - 51) x 33 = (33 x 28 ) - (33 x 51) =924 - 1683 = - 759 3. 117 x ( 12 -8) = (117 x 12 ) - (117 x 8) =1404 - 936 = 468 4. ( (-49) - 68) x 85 = ( 85 x -49) - ( 68 x 85) = - 4165 -5780 = -9945 5. -165 x ( 30 - 14) = (-165 x 30) - ( -165 x 14) = - 4950 + 2310 = -2640
= 1886 - 984 = 902
2. (28 - 51) x 33 = (33 x 28 ) - (33 x 51)
=924 - 1683 = - 759
3. 117 x ( 12 -8) = (117 x 12 ) - (117 x 8)
=1404 - 936 = 468
4. ( (-49) - 68) x 85 = ( 85 x -49) - ( 68 x 85)
= - 4165 -5780 = -9945
5. -165 x ( 30 - 14) = (-165 x 30) - ( -165 x 14)
= - 4950 + 2310 = -2640
= 41×(46-24)
= ( 41 x 46 ) - ( 41 x 24 )
= 1886 - 984
= 902
nomor 2
= (28+(-51))×33
= (28 - 51) x 33
= ( 28 x 33 ) - ( 51 x 33 )
= 924 - 1683
= 759
nomor 3
= 117×(12-8)
= ( 117 x 12 ) - ( 117 x 8 )
= 1404 - 936
= 468
nomor 4
= ((-49)-68)×85
= (- 49 - 68) x 85
= (-49 x 85) + (- 68 x 85)
= ( - 4165 ) + ( - 5780 )
= - 4165 - 5780
= - 9945
momor 5
= -165 x ( 30 - 14)
= (-165 x 30) - ( -165 x 14)
= - 4950 + 2310
= -2640
