a) 13276-(4500+3276)= 13276-4500-3276
= 13276-3276-4500
= 10000-4500=5500
b) 58264+4723-8264-723=58264-8264+4723-723=50000+4000=54000
a) 13726-(4500+3726)=13726-4500-3726=13726-3726-4500=10000-4500=5500
a,, 13 726 - ( 4500 + 3726 )
= 13 726 - 4500 - 3726
= (13 726 - 3726 ) - 4500
= 10 000 - 4500
= 5500
b, 58264 + 4723 - 8264 - 723
= ( 58264 - 8264 ) + (4723 - 723 )
= 50 00 + 4000
= 54 000
