When multiplying or dividing a negative number or variable.
Can you reverse the numbers inside an absolute value symbol?
The answer depends on the operation. The absolute value of 2/3 is not the same as the absolute value of 3/2! It does work for subtraction, though.
Does a revo 3.3 have reverse?
Yes the revo 3.3 does have reverse. There is a 3rd channel on the transmitter to allow you to switch form forwards to reverse. There is also an opti drive which stops you from going into to reverse when you are going fast forward.I have a revo 3.3 with reverse and i took out the reverse because you cannot use it in races. But if you are just messing around in your back yard or something and not racing i recommend keeping the reverse!
