I dont get what your asking?
If you would like to solve 6 * (-10), you can calculate this using the following step:
6 * (-10) = - 6 * 10 = - 60
The correct result would be - 60.
5/8=.625
2/3=.67 (rounded up)
.625/ .67 (frac.)
divide those by .67
and it's 94/1, so the answer is .94 seconds read per minute, or 1.34 seconds
Anything to the zero power is 1.
