Answer 2

Step-by-step explanation:

107×104=11128

7×4=28

7+4=11

1) multiply one's digits 7×4=28

2)adds one's digits 7 +4=11

3)write 1

one more example

102×104=10608

2×4=8 ,it needs to be two digits so write 08

2+4=6,it needs to be two digits so write 06

then write 1

--> like the above we can multiply two numbers between 100-109.
