32x18+32x32等于( )?

32x18+32x32 =(18+32)x32 =50x32 =160

原式= 32x(18+32) =32x50 =16x2x50 =16x100 =1600

1024

32x29+ 32 =32x(29+1) =32x30 =960

32X49+32=32X(49十1)

原式 =32x18+32x31+32 =32x(18+31+1) =32x50 =16x2x50 =16x100 =1600

32x18÷24 =32x(18÷24) =32x3/4 =24

答:32x18+ 32x82 =32*(18+82) =32*100 =3200

32x[275÷(23+32)] =32x[275÷55] =32x5 =160

32x18-32 =32x(18-1) =32x17 =(30+2)x17 =30x17+2x17 =510+34 =544
