Question

Which property of addition is satisfied by:
(v) $(15-12)\times 18=15\times 18-12\times 18)$

Answer 1

(v) We know that, whole numbers obey distributive property of multiplication over subtraction.
i.e.,
$(a-b)\times =(a\times c)-(b\times c)$
Hence,
$(15-12)\times 18=15\times 18-12\times 18$
Thus, distributive property of multiplication over substraction is satisfied.
