1. -15+64+36-45=             2.  27-82+43-18=       3.  -44+88-56-38 =.   4. 24-50-25+76 =.                                                  

Answer 1

1) ( 64+ 36)-(45+ 15)=40
2) ( 27+ 43)- ( 82+ 18)=-30
3)88- ( 44+56+38)=-50
4)(24+76)-(50+25)= 25

Answer 2

Let's calculate these expressions step by step:

1. -15 + 64 + 36 - 45 = -15 + 64 = 49 49 + 36 = 85 85 - 45 = 40

2. 27 - 82 + 43 - 18 = 27 + 43 = 70 70 - 82 = -12 -12 - 18 = -30

3. -44 + 88 - 56 - 38 = -44 + 88 = 44 44 - 56 = -12 -12 - 38 = -50

4. 24 - 50 - 25 + 76 = 24 - 50 = -26 -26 - 25 = -51 -51 + 76 = 25

So, the results are:

1. -15 + 64 + 36 - 45 = 40
2. 27 - 82 + 43 - 18 = -30
3. -44 + 88 - 56 - 38 = -50
4. 24 - 50 - 25 + 76 = 25
