1. Integers, rational and real numbers. WHOLE number

2. Equation a line: y=mx+b
m= slope of the line
b = y intercept (basically, where the line crosses the y axis.)

* Example: say you have equation of the line y= 2x+6 , you know that line
will go directly through 6 on the y axis. This can help you eliminate the
wrong answers quickly ie.like seeing answers where the line crosses through
say -3 or 1 you would know right away that is the wrong answer just by
knowing the y intercept).

3. Temperature formula: F*= (1.8x C*)+32 (only 1 question)

4. Know Standard Deviation
I memorized the Bells Curve and drew it on my white board ASAP. I
filled in/labelled all the percentages (34%, 13.5%. 2.5%, 0.15% & 68%, 95%,
99.7%), mean, +/-1SD, +/-2SD, +/-3SD, (may seem confusing now but once
you look at the diagram you’ll
know what I'm talking about).

Formula for Standard deviation : *This is how my brain understood how to
calculate Standard deviation outlined in Module 4.

• Standard deviation 1: Mean - SD & Mean + SD
• Standard deviation 2: Mean - (2 x SD) & Mean + (2 x SD)
• Standard deviation 3: Mean - (3 x SD) & Mean + (3 x SD)
