The real numbers are the set of numbers containing all of the rational numbers and all of the irrational numbers. The real numbers are “all the numbers” on the number line. There are infinitely many real numbers just as there are infinitely many in the other sets of numbers.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

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.

Prime number : A prime number is a natural number greater
than 1 and is divisible only by 1 and itself.
e.g.2, 3, 5, 7, 11, 13, 17 ,19 ………….etc.
Note :- 2 is the only even prime number.
12. Composite Numbers : A number, other than 1, which is not a prime number is called a
composite number .
E.g. 4, 6, 8, 9, 10, 12, 14, 15 ……….etc.
Note :1 1 is neither a prime number nor a composite number.
2 there are 25 prime numbers between 1 and 100.
To find whether a number is prime or not-
To check whether the number is prime or not,
1 We take an integer larger than the square root of the number. Let the number be ‘k’.
2 Test the divisibility of the given number by every prime number less than ‘k’.
3 If it is not divisible by any of them, then the given number is prime otherwise it is a
composite number.
E.g.= Is 881 a prime number ?
Sol- The appropriate square root of 881 is 30.
Prime number less than 30 are 2, 3, 5, 7, 11, 13, 17,19, 23,29.
881 is not divisible by any of the above numbers, so it is a prime minister.
Co-prime numbers : Two numbers are co-prime of their HCF is 1.
E.g. (2,3), (3,4) , (5,7), (3,13) etc.
Even numbers : The number which is divisible by 2 is called even number.
E.g. – 2, 4, 6, 8…………….

Nisbah
(Q)
Nombor nisbah ialah nombor dimana :
{ | p dan q adalah integer,q ≠ 0 }
Dibaca sebagai p per q, di mana p dan q adalah integer,q ≠ 0 .
Nombor nisbah boleh ditulis dalam bentuk perpuluhan, iaitu
sama ada perpuluhan terhad atau berulang.
Contoh : 0.6, 30.5, 2/3, 4/7, 0.67
(di mana palang di atas 67 bermaksud nombor 6 dan 7 ditulis
berulang iaitu 0.67676767676......)
• Rational numbers are real numbers that can be written as
a _____________ where a and b are integers and b ≠ 0.
Any rational number can be represented as a terminating or
a repeating ___________. Rational numbers are those numbers
which cannot be written as integers.
They are written as an integer divided by
another integer and the dominator is not
and both numbers do not have
common factors.
decimal
Rational numbers can be called fractions.
14. Essential Questions:
• How do you know if a number is a rational number?
• What are the properties used to evaluate rational numbers?

48. Apakah dia nombor nyata?
• Suatu nombor nyata (R) merujuk kepada sebarang nombor yang
terletak pada garisan nombor.
• Nombor nyata mengandungi semua nombor nisbah ( iaitu nombor
perpuluhan berulang yang infiniti, nombor positif, negatif dan sifar)
bersama dengan satu set nombor dipanggil nombor bukan nisbah.
51. Operasi asas terhadap nombor nyata
• Empat operasi aritmetik
• Tambah
• Tolak
• Darab
• bahagi
52. • Tokokan (Increment)
• Istilah tokokan adalah merujuk kepada situasi di mana suatu kuantiti
bertambah sebanyak satu amaun dan operasi tambah diperlukan
untuk mencari jumlah baru setelah berlaku tokokan.
53. Operasi Tolak
• Pengasingan atau mengambil keluar ( Take away )
• “Pengasingan dan mengambil keluar” melibatkan ada satu kuantiti
pada awalnya dan mengeluarkan satu kuantiti tertentu daripadanya
serta mempertimbangkan berapa kuantiti yang tinggal.
54. • Perbandingan ( Comparison )
• Perbandingan - dua set objek berasingan diberi.
• Set objek pertama disusun semula dan dipadankan dengan set objek
kedua.
• Set objek yang tidak ada pasangan dikenali sebagai baki atau beza.
55. Operasi Darab
• Penambahan Berulang
• Masalah kumpulan sama banyak atau penambahan berulang adalah
masalah biasa dalam struktur pendaraban, di mana anda melibatkan
beberapa kumpulan tertentu yang mempunyai saiz yang sama.
• Apabila kedua-dua bilangan dan saiz kumpulan diketahui (tetapi
jumlah tidak diketahui), masalah ini dapat diselesaikan menggunakan
pendaraban
56. • Luas / Tatasusunan (Area / Array)
• Masalah luas dan tatasusunan merupakan contoh masalah yang
jarang digunakan dalam struktur pendaraban.
• Luas bagi segiempat boleh dikira dengan meletakkan petak 1 unit
atau mengira secara berasingan atau mengira lebar segiempat
(bilangan unit petak dalam lajur) dan panjang (bilangan unit petak
dalam baris).
57. Operasi Bahagi
• Penolakan Berulang
• Dalam situasi pembahagian menggunakkan jenis penolakkan
berulang, anda mempunyai kumpulan yang sama saiz, anda telah
ketahui bilangan objek yang ada dalam setiap kumpulan, dan anda
diminta menentukan bilangan kumpulan.
58. • Perkongsian / Pembahagian (Sharing / Partition)
• Dalam situasi pembahagian jenis perkongsian, satu set objek
diasingkan kepada bilangan kumpulan yang sama dan anda diminta
mencari bilangan ahli dalam setiap kumpulan yang sama itu.
• Dalam hal ini, anda telah mengetahui bilangan kumpulan yang anda
ingin bentukkan, tetapi anda tidak tahu bilangan ahli yang diperlukan
dalam setiap kumpulan.
