is
In-depth Solution by BoundlessBrain!
Solution
Evaluate each number in the set:
![\[-3a = -3(-2) = 6\]](http://latex.artofproblemsolving.com/7/5/9/7595b1ed75a2b420cccc17ddf2882ba521ae48f7.png)
![\[4a = 4(-2) = -8\]](http://latex.artofproblemsolving.com/4/b/3/4b32955e5211a53280b1bf580dccf9ece43f70d6.png)
![\[\frac{24}{a} = \frac{24}{-2} = -12\]](http://latex.artofproblemsolving.com/4/3/7/4378dbd0db714c1a8232dd36fad386efe52f15af.png)
![\[a^2 = (-2)^2 = 4\]](http://latex.artofproblemsolving.com/3/7/9/37985bc2198b84808cdeab772ff864b3700e9b94.png)
The largest number in this set is
