April's blog post for November 8th 2010

HI EVERYONE! Today in Math class, Mr. Backe gave us a whole bunch of notes.

HERE THEY ARE:

Quiz 3 will be on:

• identifying rationals
  - natural, whole, integers, rational and irrational. (All belong to set of real numbers)

order of operations for all rationals

converting fractions to decimals, fractions to percent and decimals to fraction AND vice versa

solving rational # problems (to that end of 2.3 by end of the week)

Signs, signs, everywhere signs...

In math, we follow a certain order to be able to get to the same answer. (Universally) Order is usually denoted by mathematical symbols (signs). In grade 7 you learned BEDMAS.

BEDMAS is also sometimes called PEDMAS. P means Paranthesis.

Other confusing signs

• when brackets "kiss" ( ) ( ) <-- kissing, it means to multiply.
• a bracket around an integer does not necessarily mean do me first!

• a dot in the middle of two numbers can mean multiplication or be a place holder for decimals. If the dot is in the middle of the numbers
  It means multiply, it if is lower down (1.1) it is a decimal place holder.

When is a negative number negative?

a = 1

b = 2

c = 3

ALL OR SOME?

Question for tomorrow:
