16 x 7 + 14 x 2 = ?
= 16 x 7 + 7 x 4
= 7 x { 16 + 4 }
= 7 x 20
= 140
16x7+7x2x2
=16x7+7x4
=7x(16+4)
=7x20

16 x 7 + 14 x 2
= 16 x 7 + 7 x 4
= 7 x ( 16 + 4 )
= 7 x 20
= 140
16 x 7 + 14 x 2
=16*7+7*2*2
=16*7+7*4
=7*(16+4)
=7*20
=140
minh nham
16 * 7+ 7 * 4
= 7 * ( 16 + 4 )
= 7 * 20
= 140
16 x 7 + 14 x2
= 16 x 7 + 7 x2 x2
= 16 x 7 + 7 x 4
= 7 x ( 16 + 4 )
= 7 x 20 = 140
