Re: Multiplication?

Hi Sarah Rebekah 13;

Did you learn your times tables? Best way in the world is flash card games.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Multiplication?

How did you do? Do you have a question about a problem? What ones did you get wrong?

Re: Multiplication?

Here's a link to a video looking at a multiplication trick;

Unfortunately, it doesn't yet have any annotations... if you can make sense of it without them, great! If not, ask me here. I'll add the annotations later.

Re: Multiplication?

If you forget one of your
multiplications like 5 times 7,
you can figure it out by adding
5 + 5 + 5 + 5 + 5 + 5 + 5
or
7 + 7 + 7 + 7 + 7
Notice seven 5's or five 7's.
