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

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)

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
