If you have no negative or an even amount of negative signs in a division question, the quotient is positive.

There are 2 types of division:

Partitive Division:

Justin Sunga Term 2 Reflection .

In term 2 I've learned a lot about 3D Shapes and the formulas for finding there volumes and areas.
EX: Volume of Cylinder =Pi x Radius x Radius x Height, Area of Prisms = Length x Width, Volume of Rectangular Prism = Length x Width x Height. We also had to learn how to make nets, 3D shapes.

I mostly struggled on the formulas because there were a lot of them and I had to remember all of them, but with some practice I finally remembered all of them.

Next term I will try to focus on my homework and study more about what we will learn. I will also try to get my grades higher and continue doing a good job on tests.

I've learned so much from term 2, that the surface area of a shape is the sum of all the areas and can and can determine the Surface Area and Volume of a 3D shape. And that Volume is the amount of space a 3D shape has, and probably a lot more about 3D shapes.

Justin Sunga Final Percent Post

A percent means out of 100 it can be represented as a decimal or fraction.

example - 25% means 25 out of a 100 and , or 25/100 or 0.25

4.1 Representing Percents
To be able to represent a percent you need to use a grid chart out of 100, one shaded grid chart means that all the squares shaded in represents 100%. If you want to show a percent that is larger than 100% you need to shade in more then one grid chart. To represent a percent between 0% and 1% you would shade in one square.
Fractional Percent - A percent that includes a portion of a percent.
example - 1/2%, 0.42%, 73/8%, 3/4%, 4.5%

4.2 Fractions, Decimals, & Percents
Fractions, decimals, and percents can be used to represent numbers in many ways.
Percents can be written as fraction as decimals.
example - 1/2% = 0.5% 0.5% = 0.5/100 = 0.005
150%= 150/100 =1.5 or 11/2
423/4%=42.75% 42.75%=42.75/100 =0.4275

4.3 Percent of a Number
You can use strategies like doubling,halving, and dividing by ten to find the percent of the number.
To calculate the percent of a number, write the percent as a decimal and then multiply the number..

(+4) + (-2) = +2
Positive (4) Negative (2) = Positive 2
Have 4 Owe 2 = have 2
Standard Form : 4 - 2 = 2.

Making A Zero Pair:
An example of a zero pair is (+1) + (-1).
A negative and a positive can make a zero pair because it is oppisite from each other.

Even: When you have an even amount of negative factors, the product is positive.

Ivan's Term 2 Reflection.

What I’ve learned in term two was, total surface area, and volumes. I’ve struggled a lot in surface area at first I didn’t get it until Mr. Harbeck explained it right. Volume I was comfortable with, but the cylinder. I’ve struggled a lot on cylinder, because I hate them. But once I got to know the formula, I studied it so I can learn it better. For the next term, I will try my hardest to get my grades up. I did well on the Surface Area because I understood them a lot, but the net was complicated, we had to draw them out. I didn’t like the net at first, until I practiced drawing the nets, I got to know the nets a lot better, and in term 2 my test improved. This term, I would like to work better, and improve my test marks a lot better.

I will post audioboo once I get that flash thingy for the computer.

How I would solve this equation: (+5) x (-3) + (-6) / (+3)

First, I would follow the rules of BEDMAS, so I'd put square brackets around (-6) / (+3)

After, I would solve what (+5) x (-3)

Then I would add the two answers together which would equal to -17.

(+5) x (-3) + [(-6) / (+3)]

-15 + -2
