Yesterday's Tomorrow's Today (lvl2+ and 4+) (HINTS added)

Greetings Steamgifters!

I am j3rc from the year 5102. In my time there is no war, no hunger, no disease, no evil, no Brussels sprouts, and everybody is beautiful. Unfortunately we still have not been able to eradicate one thing, Dyscalculia.
I was just cruising around in my Einstein-Rosen EMC2 time-displacement-apparatus when, I guess, I hit the wrong buttons, just like the legendary Martin Seamus McFly from the Sacred Trilogy, and I too ended up in 2015 and now I am kind of stuck here.

You see, I wormed into what you call a "traffic light", we do not have such archaic measures for we don't have the chaotic flow of trans-portation that your time suffers from. Now my flux-capacitor and temporal conduit are busted and I don't have my portable replicator with me to make new ones.
Fortunately I did bring my Gratedrupe ϱ temporal communicator, it allowed me to hack into this compatible account name and post this message. However I forgot to charge my communicator so it only let me send this message from here in December 2015 to you over in January 2016. I tried charging it at the Genius Bar, but I guess genius means something else in this time cos all they did was try and sell me some fruit. Now I am unable to contact wormholeside rescue for assistance.

There is however a contingency plan in place for unforeseen situations like this. We hide an emergency repairs kit in every year on the first day of that year, and it disintegrates on the last day of the year, it's all biodegradable you see. The good news is; it should be nice and fresh right now, the bad; my Dyscalculia will prevent me from getting it. I am going to require your assistance. Instead of a map telling us where to find it we like hiding stuff like that behind a cryptic set of questions. Once those are answered you will get directions on what to do.

The questions can be accessed through here.
