Hey there!!

Let's learn the basic formula -

( a + b ) ( a - b ) = a² - b²

Let's break 24 × 16

We can write this as

( 20 + 4 ) × ( 20 - 4 )

This is in the form of ( a - b ) ( a + b )

Hence, ( 20 + 4 ) ( 20 - 4 ) = ( 20 )² - ( 4 )²

= 400 - 16

384

The required answer is 384

Hope my answer helps!!
