Question

Find the product, using suitable properties:
$25\times (-50)+(-50)\times (-32)$

Answer 1

$25\times (-50)+(-50)\times (-32)=(-50)\times 25+(-50)\times (-32)...usingtheproperty(b\times a=a\times b)=(-50)[25-32]...usingtheproperty(a\times b+a\times c)=a(b+c)=(-50)\times (-7)=350$ which is the required answer
