Special Numbers: 0 and 1

Genesis 1:3-1:4 Among the integers, I believe 0 and 1 are the most interesting. Adding 0 to any number does not change that number. More precisely, a  + 0 =  a   and 0 + a = a for all integers  a . In group theory terminology, 0 is the identity element under addition or the additive identity. You may ask, is there also such a thing as multiplicative identity? Yes, there is! In fact, by the title of this post you probably know what it is. One is the multiplicative identity. That is,  a  x 1 =  a  and 1 x  a  =  a  for all integers  a . Does 0 play an important role in multiplication? Yep! Multiplying by 0 always yields 0. More precisely,  a  x 0 = 0 and 0 x  a  = 0 for all integers  a. We may also say that 0 the absorbing element under multiplication. A field has at least 2 elements A field is a set together with two operations satisfying certain conditions . An example of...

A case for overpreparation

In our student teaching class, my groupmate and I were tasked to give a report on the different aspects of student teaching. As part of our report, the different forms that a teacher has to fill in were discussed. Fortunately, I looked up the names of these forms. Unfortunately, however, I did not know what they were for. So our instructor herself had to explain their purpose. She also informed us that some school forms were already obsolete and were already replaced and renamed by the DepEd . Screen capture from: Student Teaching Worktext by Atienza, et.al. The idea of downloading the forms and including them in our presentation came to mind, I just did not want to overprepare. I mean, what good would it be if I go above and beyond what is required for me to pass this course? It's not like I'm vying for honors; I already graduated a few years ago. I'm only here to pass this course and hopefully learn something along the way that will help me become a better teacher...
