The answer to this question would be 39..here is why:
First you multiply 23 x 3..because multiplication or division always comes before addition or subtraction.
Second, you get the product from 23 x 3 which is 69..and you subtract 30 from that.
Last, after you do that you get an over all answer of 39..
Hope this helps!!
