    Start with what’s in the parenthesis. Then do PEMDAS (multiplication is next) and then do the division. And subtraction

    Answer:

    -7

    Step-by-step explanation:

    Remember Pemdas

    1. Parenthesis

    2. exponents

    3. multiplication

    4.division

    5. addisiton

    6. subtraction

    So, first do the parentheses first and since 3×8 comes first do that which it will be 24 and then subtract 24-7= 17

    When you get this we then have to divide it is whatever comes first for multiplication or division from left to right we have to do first and in this case 34divded by 17 which is 2.

    The next step is multiplying 2×3 which gives us 6

    and now we start from beginning again which is 1 minus 2 which gives use  – 1 and we subtract again -1 subtract in other words now add which gives use negative -7 as our final number

    -7
