It is used but not actually "read" like other textbooks?
It has roots entangling it?
Note that (-9)^2 = -9*-9 = 81 + 2^3 = 81 + 2*2*2 = 81 + 8 = 89.
10^5 + 10^2 = 100,000 + 100 = 100,100.
This requires lots of distributing!
What do you mean? Like 2*2*2 --> 2^3?
You would just use - (^-3, for example).
On the on-site calculator, make sure it is set to degrees mode on the bottom and do atan(0.83).
757 - 596 = ?
?*596 X 100 = %
DS, 1/4 is 0.25.
Get common denominators:
-5/1 --> #/4...to get #, you need to multiply -5 by 4.
Then, simply subtract. Note that your answer will be negative.
