Question

Find the value of $20(13+4)$. Then, using the variables $a,b,$ and $c$, show the distributive property of multiplication over addition.

Answer 1

$20(13+4)$
$=20\times 13+20\times 4$
$=260+80=340$

Now, Let us consider, $a=20,b=13,andc=4$
$\because 20(13+4)=20\times 13+20\times 4$
$\therefore a(b+c)=a\times b+a\times c$
The above expression is showing distributive property of addition over multiplication, where; $a,b,andc$ are variables.
