Answer 1

43-(1,7-16)=43-1,7+16=57,3
57-(4в+17а)=57-4в-17а
2,67-(8,04-7,33)=2,67-8,04+7,33=1,96
12,14-(3,5+6,14)=12,14-3,5-6,14=2,5
-8,76-(3,25-10,76)=-8,76-3,25+10,76=-1,25
(3,98-7,36)-(5,98-10,36)=3,98-7,36-5,98+10,36=3-2=1

Answer 2

1. 43 - (1.7 - 16) = 43 - (-14.3) = 43 + 14.3 = 57.3

2. 57 - (4B + 17a) = 57 - (4B + 17a)

Since we don't have specific values for 'B' and 'a', we can't simplify this expression further without additional information.

3. 2.67 - (8.04 - 7.33) = 2.67 - 0.71 = 1.96

4. 12.14 - (3.5 + 6.14) = 12.14 - 9.64 = 2.5

5. -8.76 - (3.25 - 10.76) = -8.76 - (-7.51) = -8.76 + 7.51 = -1.25

6. (3.98 - 7.36) - (5.98 - 10.36) = -3.38 - (-4.38) = -3.38 + 4.38 = 1
