12 x 68 + 12 x 32 + 100
= 12 x (68 + 32) + 100
= 12 x 100 + 100
= 1200 + 100
= 1300
12 x 68 + 12 x 32 + 100
= 12 x ( 68 + 32 ) + 100
= 12 x 100 + 100
= 1200 + 100
= 1300
mình nha
12 x 68 + 12 x 38 +100
=12 x (62+38)+100
=12 x 100+100
=13 x 100
=1300
12 x 68 + 12 x 32 + 100
= 12 x ( 68 + 32 ) + 100
= 12 x 100 + 100
= 1200 + 100
= 1300
tk mình nha
12x68+12x32+100
=12x(68+32)+100
=12+100+100
=1200+100
