a) 425 - 84 - 16
= 425 - (84 + 16)
= 425 - 100
= 325
b) 821 - 73 - 27 - 21
= (821 - 21) - (73 + 27)
= 800 - 100
= 700
c) 475 - (75 - 36)
= 475 - 75 + 36
= 400 + 36
= 436
d) 573 - (73 - 24)
= 573 - 73 + 24
= 500 + 24
= 524
a) 425 - 84 - 16 = 425 - ( 84 + 16 ) = 425 - 100 = 325
b) 821 - 73 - 27 - 21 = ( 821 - 21 ) - ( 73 + 27 ) = 800 - 100 = 700
c) 475 - ( 75 - 36 ) = 475 - 75 + 36 = ( 475 - 75) + 36 = 400 + 36 = 436
