Question

Associative property holds good for which of these operations?

• A. Addition
• B. Subtraction
• C. Multiplication
• D. Division

Answer 1

Answer: (A), (C)

The correct options are
A Addition
C Multiplication

Associative property holds good for integers under addition and multiplication.
a + (b + c) = (a + b) + c
$a\times (b\times c)=(a\times b)\times c$
But it is not valid under subtraction and division.
For eg., consider integers 1, 2 and 3.
1-(2-3) = 1-(-1) = 2 but
(1-2)-3 = -1-3 = 4
Similarly, consider integers 9, 3 and 2.
$(9÷3)÷2=\frac{3}{2}$ but $9÷(3÷2)=(9\times 2)÷3=6$
