Exam Review: Integers

1. 7+3=10
2. 8-5=3
3. 2+4=6
4. 3-9=(-6)
5. 7+(-3)=4
6. 8-(-5)=13
7. 2+(-4)=(-2)
8. 3-(-4)=12
9. (-7)=3=(-4)
10. (-8)-5=13
11. (-2)+4=2
12. (-3)-9=12
13. (-2)+-(-4)=(-6)
14. (-8)-(-5)=(-3)
15. (-7)+(-3)=(-10)
16. (-3)-(-9)=6

Use integers to discribe the main floor, the basement, and the third floor.

(-1, o, 2)

Give each an example for:

opposite integer- (+1, -1)

zero pair- (+1)~(-1)

addition statement- (-3)+2=1

subtraction statement- (-3)-2=(-5)

Give an example for each:

(+)+(-)=(+)

(+)+(-)=(-)

(+)-(-)=(+)

(+)-(-)=(-)

~Sorry that I didn't put any pictures of the integer chips, I was in a rush and I thought it would take to much time to do them all~

Exam Review Study Guide-

DEFINE:
Perpendicular- Describes lines that intersect at right angles. (90 degrees)
Parallel- Describes lines in the same plane that never crosses or intersect.
Intersecting- Lines that cross at any angle.
Perpendicular Bisector- A line that divides a line segment in half and meet at 90 degrees.
Angle Bisector- The line that divides an angle into 2 equal parts.
Acute angle- An angle that is less than 90 degrees.
Obtuse angle- An angle that is greater than 90 degrees and less than 180 degrees.
Right angle- is exactly 90 degrees.

Formulas :
Area of a triangle= bxh divided by 2.
Area of a parallelogram= bxh




Base- 50m Height-20m. Find the Area of the Parallelogram.
A= bxh
A= 50x20
A= 1000m "squared"

Find the area:
A= bxh/2
A= 10x12/2
A=120/2
A= 60m "squared"




CONVERT:
fractions->decimals->Percents
3/4 = 75/100= 0.75/1

- Fractions are out of any whole number.
-Percentages are out of 100
-Decimals are out of 1

2/5= 40/100 --> 2/5=0.4/1
