43.17 + 29.57 + 13.43 + 57 = (43.17) + (13.43) + (29.57) + 57 = 43. (17 + 13) + 57. (29 + 1) = 43.30 + 57.30 = (43 + 57).30 = 100.30 = 3000.
43.17+29.57+13.43+57
=43.17+29.57+13.43+57.1
=43.(17+13) + 57.(29+1)
=43.30 + 57.30
=(43+57) .30
=100.30
=3000
43.17+29.57+13.43+57= 3.500.2
=43.(17+13)+57.(29+1)
= 43.30+57.30
= 30.(43+57)
= 30.100
= 3000
