Question

Multiply by $475$ by $64$

Answer 1

$475\times 64$ can be written as:
$=475\times \left(100-36\right)$ (By using distributive property: $a\times b=a\times \left(c\times d\right)$)
$=475\times 100-475\times 36$ ( By removing bracket)
$$\begin{gathered} =47500-17100 \\ =30400 \end{gathered}$$
Hence the value of $475\times 64=30400$
