Question

Find the product by suitable arrangement:
$8\times 291\times 125$

Answer 1

We can arrange the calculation in such a way that it becomes easy and quick to find the answer.

$8\times 291\times 125$

We can find the product of 8 and 125 first as we know that will give 1000. Multiplying any number by a thousand will result in the same number with 3 additional zeros the end.
= $(8\times 125)\times 291$

= $1000\times 291$

= $29,000$
