Question

Solve it using distributive property.

$18\times 22-18\times 18$

Answer 1

Using distributive property of multiplication over subtraction:

$\Rightarrow$ $\mathrm{a}\times (\mathrm{b}-\mathrm{c})=\mathrm{a}\times \mathrm{b}-\mathrm{a}\times \mathrm{c}$

Now, $18\times 22-18\times 18$

Taking out $18$ common

$=18\times (22-18)$

$=18\times 4$

$=72$

Hence, the result is $72$.
