Question

Find the product of the following using some quicker grouping

$5\times (-10)\times 27$

Answer 1

Given

$5\times (-10)\times 27$

First we simplify the first two terms and then the remaining two terms

$5\times (-10)\times 27$$=(5\times (-10\left)\right)\times 27$

$5\times (-10)\times 27$$=(-50)\times 27$

$5\times (-10)\times 27$$=-(50\times 27)$

$5\times (-10)\times 27$$=-1350$

Hence, the correct answer is $-1350$
