134 x 100 + 250 x 100 - 84 x 100
= (134 + 250 - 84 ) x 100
= ( 384 - 84 0 x 100
= 300 x 100
= 30000
a, 13104
b,134*100+250*100-84*100=100*(134+250-84)=100*300=30000
134*100+250x100-84x100
=100x(134+250-84)
=100x300
=30000
a) 4 x 126 x 26
= 504 x 26
= 13104
b) 134 x 100 + 250 x 100 - 84 x 100
= 100 x ( 134 + 250 - 84 )
= 100 x 300
= 30000
