A Snapshot of Hindi Class 7 Maths NCERT Book (PDF) Chapter 1:

Important Points:

⇨ Integers are closed for addition & subtraction both. That is, a + b &

a – b are again integers, where a & b are any integers.

⇨ Addition is commutative for integers, i.e., a + b = b + a for all integers

a & b.

⇨ Integer 0 is the identity under addition. That is, a + 0 = 0 + a = a for every

integer a.

⇨ Integers are closed under multiplication. That is, a × b is an integer for any two

integers a & b.

⇨ Addition is associative for integers, i.e., (a + b) + c = a + (b + c) for all integers

a, b & c.

⇨ Multiplication is commutative for integers. That is, a × b = b × a for any integers

a & b.

⇨ The integer 1 is the identity under multiplication, i.e., 1 × a = a × 1 = a for any

integer a.

⇨ Multiplication is associative for integers, i.e., (a × b) × c = a × (b × c) for any

three integers a, b & c
