15, 66 + (17, 93 - 12, 23); (88, 16 - 69, 55) + 16, 15; 100 + (83, 99 - 34 + 63); 58 + (45, 63 - 21, 21); (55, 65 - 45, 09) + 7; (46, 3 - 34) + 54, 56; 43 + (16, 81 - 14, 81); (110, 3 - 79) + 25, 05; (29 - 11, 89) + 15; 89, 99 + (89, 99 - 89, 99)

Answer 1

1. 15,66+(17,93-12,23)=15,66+5,7=21,36;
2. (88,16-69,55)+16,15=18,61+16,15=34,76;
3. 100+(83,99-34+63)=100+112,99=212,99;
4. 58+(45,63-21,21)=58+24,42=82,42;
5. (55,65-45,09)+7=10,56+7=17,56;
6. (46,3-34)+54,56=12,3+54,56=66,86;
7. 43+(16,81-14,81)=43+2=45;
8. (110,3-79)+25,05=31,3+25,05=56,35;
9. (29-11,89)+15=17,11+15=32,11;
10. 89,99+(89,99-89,99)=89,99.
