Answer 1

a) 1024,707 + (1043,24 -347,001) + 101,031 =

= 1024,707 + 696,239 + 101,031

= 1720,946 + 101,031

= 1821,977

b) (102 380 - 2007,35) - (0,03 - 0,001) - 100 000,621 =

= 100372,65 - 0,029 - 100000,621

= 100372,621 - 100000,621

= 372

c) 59,26 + 143,87 - (43,7 - 17,86) - 107,29 =

= 59,26 + 143,87 - 25,84 - 107,29

= 203,13 - 25,84 - 107,29

=177,29 - 107,29

= 70
