Math Sucks!

Ok so I have an online consumer business math class I take and....IT SUCKS. "oh well its filled with things you need to learn about life like taxes..." isnt that what my receipt was printed for? lol whatever happened to going to the store and seeing something for 4.70 and just rounding it to 5? lol THEN you KNOW you have plenty of money, who has time to calculate it anymore? Yes people like i'm REALLY going to walk into mcdonalds and say...."oh so a Big n Tasty is 3.80.....with sales tax being 4%.....and then a city tax of 1%....and a cow tax of .5%.....that'll be...." lol yea I can REALLY see myself doing that LMAO. Just had to share that.....and omg i'm listening to "sure fire winners" by Adam Lambert.....RESPECT THE ADAM! =)
