Please i need help in this sb

The first question the answer is 15.
This happens because 2×8 = 16. After that you multiply 16 by half. What do you do that the answer is eight then you add seven and get 15.

For the second question you do -6 times negative one. After that you’ll get six. Then you would have to multiply it by -2 and get -12. Then you add -12+3 and then you get -9. Your answer is -9

For the third question you would add 7+3 and get 10. Then you would have to multiply it to the second power and get 1000. Then you would have to add 1000 with four. Then you multiply seven by -2 and multiply that by four. Then you would get -56
Your answer would be -56.

It was very complicated. If I get something wrong I am sorry. I hope I helped.

#1=15 #2=-9 #3=44

Step-by-step explanation:

1/2 times 2 times 8 + 7      #2:-2(-1)(-6)+3                   #3:  (7+3)^2 +4(7)(-2)

1/2 times 2 = 1                           -2times -1=2                                 (10)^2 +4(7)(-2)

1 times 8= 8                              2(-6)+3                                           100+4(7)(-2)

8+7=15                                     2times -6=-12                                   100+28(-2)

                                               -12+3=-9                                            100+-56

                                                                                                            44
