Question 2(b)

Find the product by suitable arrangement:

$4\times 166\times 25$

Answer 1

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

$4\times 166\times 25$

We can find the product of 4 and 25 first as we know that will give 100. Multiplying any number by hundred will result in the same number with 2 additional zeros at the units and tens place
= $(4\times 25)\times 166$

= $100\times 166$

= 16600
