What math equation using 1 2 0 and only multiply and divide will get the answer of 30?

It is not possible.Division by 0 is not defined and multiplication by 0 will result in the answer being 0. After that, no amount of multiplication or division will make any difference.Division or multiplication by 1 makes no difference to a number answer.So, all you can do is divide or multiply by 2.That will generate all the integer powers of 2 but 30 is not one of them. 120 divided by 2 divided by 2 = 30

What is the difference between multiplication and division?

Multiplication, is when you give the same amount of pieces to everyone. Division, is when you divide among the pieces that you have. (This may sound confusing, here are a few examples.) Multiplication 9 x 3 = 27 There were 9 people. I gave them 3 books each. In total, if you count up all the books, it will total up to 27. Division 9 / 3 ( / = divided by) = 3 There are 9 books. I give each each person 3 books. If you divide, you will get 3 as your answer. 3 people got books.
