Scribe Post November 4th?

Tuesday, November 4, 2008
Today in class we learned about Square brackets. Basically, square brackets are just a way of showing that you have to figure out the answer inside the brackets before doing anything else. For example:


[(8+1) + (5+6)] + 7 = ?



Step 1. Add the numbers inside the regular brackets, and bring down the addition sign.



[8+1) + (5+6) + 7



[9 + 11] + 7


Step 2. Add the two remaining numbers (Only one integer will survive, as Harbeck likes to say) then figure out the rest of the problem.



[(8+1) + (5+6)] + 7



[ 9 + 11] + 7

20 + 7 = 27



The answer is 27.




Below are some more examples..enjoy. (As if!)



12 - [(-2-4) - (10 + 7)]

12 - [ -11 - 28 ]

12 - - 39 = 51



* Note: It may help if you make the two minus signs into one positive. (- - = +)



[(4+7) + (2+2)] + 6

[ 11 + 4 ] + 6

15 + 6 = 21





Well, there is my Scribe Post. Now comes the fun part, picking the next scribe. Unfortunately, I'm pretty sure I'm the last person before we start a new rotation, so everyone is now free to be picked xD Therefore, the next scribe is... Nicole SR (Sorry, I think. :P)
