Question

Need help with 2&3 I don't get ir

Answer 1

For 2 divide, then do the subtraction and multiplication..
6 / 2 = 3
1-2+15=16
for 3, multiply inside of the parenthesis..
8x2=16 and subtract 3.
16-3=13..

Answer 2

okay for 2, you have to go in order of PEDMAS. so divide 6 by 2 first. then subtract that from 1 to get -2+15 this will end with 13 for your answer.

for 3, the bars on the outside of the question mean that no matter what is inside them, the final answer is positive. so 8 times 2 is 16, 3-16 is -13. inside those bars. those bars simplify it to 13 for your answer.

so for the answers to both questions, you will have 13. i hope this helped :)
