The first one u circled is a single rotation
The answer is -652.39 try that answer
Put simply, you have to work backwards in making the equations. Start with the product of 8/3 and 9.
*9 Next take 1/4 of that. This can be done in two ways, either multiplying by 1/4:
(
*9)*
, or dividing everything by 4.
(
*9)/4
Finally, subtract three.
The final equation would read:
((
*9)*
)-3Using PE(M/D)(A/S), we'd start with

*9
3 and 9 cancel out to be 1 and 3, leaving us with

, or 8, and 3 and this part of the equation reading 8*3, which is 24.
The next step is

, which is 6.
Lastly we subtract 3 from six, leaving us 3.
Not really, still one in every 2 people will be able to drive in college, the same as in highschool. They are mathematically equally likely! Hope that helps :)
