Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

6. Rules for Integers
• When Parenthesis ( ) are
involved we get to doodle!
• This is where you need to draw
some faces. (Bet you didn’t know
you’d be doing Art in Math!)
7. Rules for Adding & Subtracting Integers
Continued
• When you multiply a (+ x -) you get a (-).
• When you multiply a (- x -) you get a (+).
• When you multiply a (+ x +) you get a (+).

10. • Reciprocal: Flipping of a fraction.
• Rational Number: All real numbers… -
3, -2, -1, 0, 1, 2, 3…
• Absolute Value: Two lines on either
side of a number asking how far away
from zero.
• Product: To multiply
• Quotient: To divide
11. Rules for

• The product of two integers with
different signs is NEGATIVE.
12. Rules Summary for
Multiplication
• Positive x Positive = Positive
• Negative x Negative = Positive
• Positive x Negative= Negative
• Negative x Positive = Negative
13. Let’s Practice “Multiplication”

14. Did you know that
the rules for
multiplication and
division are the
same?
15. Rules for
Dividing Integers (÷)
• The quotient of two integers
with the same signs is POSITIVE.
• The quotient of two integers
with different signs is NEGATIVE.
18. • Denominator: Bottom number of a
fractions.

simplified and reduced fully.
• Reduce: To divide the top and bottom
number of a fraction by the same number.
• Simplify: To make an improper fraction
proper.
26. Reduce if you can:

• Multiplicative Inverse Strategy: Moves
part of the term to the other side.
31. Solve the following equation for x:
x – 4 = 9
+ 4 +4
x = 13
We are able to get the x by itself
by ADDING 4 to each side!
32. Solve the following equation for p:
p + 7 = 21
- 7 - 7
p = 14
We are able to get the p by itself
by SUBTRACTING 7 from each side!
33. Solve the following equation for m
3 m = 18
• Divide both sides by 3 and simplify --
your work should look like this :
3 m = 18
3 3
m = 6
34. Solve the following equation for n:
2n = 3
5 7
• Multiply each side by the inverse of 2

35. • Variable: A letter or symbol that stands for an
unknown number.
• Terms: Parts of an algebraic expression of an
equation separated by operations.
• Coefficient: The number in front of a variable.
• Like Terms: Terms that have the same variable.
• Constant: A number not attached to a
variable.
• Combining Like Terms: Putting together terms
that have the same variable.
36. Rule 1: Each action should get the letter (variable) closer
to being alone.
Rule2: Additive inverse strategy moves the opposite of
the whole term to the other side.
>change signs - cancel – keep or put with a like
term
Rule 3: Multiplicative inverse strategy moves part of a
term to the other side.
>if a number is next to variable – divide
>if a number is below variable - multiply
Rule 4: Combining like terms put terms with same
ending together that are on the same side of the equal
sign.
