Properties of Addition and Subtraction of Integers

Q.

Associative property holds good for only $3$ numbers.

1. True

2. False

Q.

Which of the following options demonstrate the associative property for integers?

1. (a) + (b) + (c) = a + b + c

2. (a + b) + c = a + b + c

3. (a + b) + c = a + (b + c)

4. (a + b + c) + d = a + (b + c + d)

Q. Which of the following is an example of the associative property of addition?

1. $a+(b+c)=ab+ac$
2. $a+(b+c)=b(a+c)$
3. $a+(b+c)=(a+b)+c$
4. $a\times (b+c)=ab+ac$

Q. Which of the following is an example of commutative property?

1. 21 $\times$ 1 =21
2. 5 $\times$ (6 + 7) = 5 $\times$ 6 + 5 $\times$ 7
3. 12 + 32 = 32 + 12
4. 12 + 0 = 12
