"Hey chris, just a quick question regarding about the time variable example. when you set 1). time = 90, then added 20 by 2). time = time + 20 are you changing the value of the variable, time, with second line 2). time = time + 20? if so, can the same concept be applied elsewhere such as in a string? P.s thanks to you, i'm ahead of the class and already have a good grasp on how to start my first project!!!"
