I think you mean Baseball bat. In the younger leagues you can get a bat that is a drop 10. In the older leagues, it is usually a drop 3.
It is 9*6 minus 7 = 47
6/7 minus 2/6 is 11/21
6 minus 6 is 0. 0 divided by 7 equals 0. It is zero.
6 over 7 minus 5 over 7 is 1 over 7.
6*8-6+3-7 =48-6+3-7 =48-3-7 =38

-6 - -7 = -6 + 7 = 7 - 6 = 1.
Seven minus -6 is 13.
7 - 6/7 = 49/7 - 6/7 = 43/7 = 6 and 1/7
