72.69+18.47-8.47-22.69
=(72.69-22.69)+(18.47-8.47)
=50+10
=60
(72,69+18,47)-(8,47+22,69)
=(72,69-22,69)+(18,47-8,47)
=50+10
=60
( 72,69 + 18,47 ) - ( 8,47 + 22,69 ) = 91,16 - 31,16
= 60
( 72,69 + 18,47 ) - ( 8,47 + 22,69 )
= 72,69 + 18,47 - 8,47 - 22,69
= ( 72,69 - 22,69 ) + ( 18,47 - 8,47 )
= 50 + 10
= 60
!!!
= 72,69 + 18,47 - 8,47 - 22,69 = (72,69-22,69) + (18,47-8.47) = 50 +10 +60
( 72,69 + 18,47 ) - ( 8,47 + 22,69 )
= 72,69 + 18,47 - 8,47 - 22,69
= ( 72,69 - 22,69 ) + ( 18,47 - 8,47 )
= 50 + 10
= 60
