The link points to a video that shows a standard way of doing this.
2 *21=42
A multiplacation sentence is excactly what it says it is! EXAMPLE: 9x9=? 1x9=? 3x8=? That is a multiplacation sentence.
4 X 2 = 8
As a product of its prime factors: 2*5*89 = 890
the person who invented multiplacation is very smart and takes the easy way
draw two dots and a line beetween them.
4x+6=18
1*16, 2*8, 4*4, 1/2*32, etc.
Inverse means opposite so division is the opposite of multiplacation
the product
answer to a multiplacation equation
Maybe Multiplacation is the most struggling things in math but once you learn multiplacation you will know division and trust me you will have to use multiplacation or divsion in the furture but, if your in elementary you get use to it and get better and better!! Good Luck!!:)
