Answer 1

Answer:

thirteen multiply by nineteen is 247

Answer 2

Answer:

247

Step-by-step explanation:

$13\times 19$

Splitting the number we get

$=(10+3)\times (10+9)$

Splitting is done by taking one number as 10. This makes it easy for multiplication

From the distributive law of multiplication we get

$=10(10+9)+3(10+9)\\ =10\times 10+10\times 9+3\times 10+3\times 9\\ =100+90+30+27\\ =190+57\\ =247$

Hence, $13\times 19=247$
