You can put this solution on YOUR website! .
Regarding first question, multiply two given numbers.
About the second question, which is TOTALLY different - please, do not pack different questions in one post.
For your info: I don't know NO ONE educational site/forum, which would allow it.
Did not see no one such forum.
For some reason, in all other forums, visitors show respect to tutors
by asking only one question per post, in accordance with common sense
and normal rules of respectful communication.
And only here they allow themselves an extreme degree of disrespect to tutors,
by packing an unlimited number of questions in one post.
What is the matter ? - - - I think that the matter is in tutors.
Would the tutors have one common reasonable right position,
the order at the forum could be established in two days.
