Given that a*b = ab-b/a
Evalute
1)-3+-4*8 is it 32-8/4=6?
2)2*(4*8) is the ans 64?

it means ab minus B divided by A

  • Math (bobpursely) -

    Well, then the * is an operator, so
    1) -3+-4*8=-3+ -32-8/-4=-3-32+2=-33 as I see it.

    I don't get either of your answers, but frankly, I am not certain of the function.

    ab minus b divided by a could be
    (ab-b)/a or ab - (b/a)

  • Math (bobpursely) -

    I get the same answers as Mr. Pursley:

    If a*b = ab - b/a,
    1)-3+-4*8 = -3 + (-4)*8 = 33
    2)2*(4*8) = 2*(30) = 45

    if a*b = (ab-b)/a,
    1)-3+-4*8 = -3 + (-4)*8 = -3 + 10 = 7
    2)2*(4*8) = 2*(6) = 3
