For multiplication I have learned multiplication long ways and short ways.Doing it long ways is with a grid.First you expand the first number that you are multiplying {factors}and then you multiply the number you expanded.Like 56 and 42 you would multiply 50 and 40=2,000.Then you would multiply 50 and 2=100.Next you would multiply 6 and 40=240 then multiply 6 and 2=12.Then add up 112+2,240 and get the answer that’s how you do it the long ways.Short ways is a little easier cover up the 4 and multiply 6 and 2=12 put the 2 under the 2 and carry the the1 above the 5.Then you x out the the 2 and 1 and multiply 4 and 6=24 so you put the 4 down carry the 2.Then do 5 and 4=20+2=22.For multiplication the answer to a multiplication problem is called a product.
