1. One times anything will always equal the second number:
1x3=3
2. The outcome of any number times two will always be even.
2x7=14
3. There is a song by NSYNC that helps remember the threes.
4. Rythm is "Row Row Row your boat"
Four, Eight, Twelve, Sixteen
Twenty, Twenty-four
Twenty-eight, thrity-two, thirty-six,
forty, forty-four
5. When five is multiplied oddly, the outcome is always odd and ends with a 5. When 5 is multiplied evenly, the outcome is always even and ends with a 0.
6. Outcome is never odd.
7. Hmm . . I don't know just remember them x]
8. This one is blank too . .. sorry x]
9. Hold out your hands so you can see your palms and the thumbs are on the outsides.
When you multiply nine times anything you have to put that finger down so lets see:
Your left thumb will stand for 9x1.
Your left index finger will stand for 9x2.
Your left middle finger will stand for 9x3
And so on, but you can only use this until 9x10.
Now to count.
Put down your left thumb. Anything to the right of the finger you put down is ones. And anything to the left of the finger you put down is tens. Now count how many you have on the right and the left.
You should have nine x]. So that's nine, the answer to 9x1.
Let's try putting down the index finger.
Now you have one to the left and eight to the right.
Add it together and you get = 1.8 or eighteen where the "." is the finger you put down. 18 is the answer to 9x2.
This will work everytime you do it, but only until 9x10 where you have none on the right and 9 tens [90] on the left.
10. Just add a 0 to the end of the number you're multiplying.
10x7=70
10x22=220
11. Double the digit that you're mulitplying against. Only if it is a single digit, this will not work with a two number digit.
11x3=33
12. Refer to a clock.

Multiplication is simply fast adding. 5x8 is the same as 5+5+5+5+5+5+5+5=40. If you know some of the facts, others can be found through double and half. Example: 4x6 If you double six and "half" four, the problem becomes 2x12=24. Fives are really easy to double and half, because doubling 5 gets you ten, so if it's something like 5x8, half of 8 is 4 and 4x10=40, so 5x8=40.
Nines can be thought of as "one group less than" 10. Example: 9x7 is the same as 10x7 but with "one less 7", so 10x7=70 and 70-7=63, so 9x7=63.
One thing that really helped me was to create a "table" with 10 rows and 10 columns. I numbered from 1-10 across the top and down the side, then filled in from memory what each of the boxes should be (down the 4 column to the 7 row, answer is 28).
A lot of these are really easy once you know the tricks, so fill in what you know and see how little you really have left to learn. However, if you still have more than 50 to learn, start with one group (say, multiplying by 7) and learn those backwards and forwards. Fill them in and then move on to another group.

You are not dumb. Many people have problems with the multiplication tables. Take each problem, one at a time write it on a piece of paper and hang it up where you can see it. Practice it throughout the day until you get that one done, then start on the next. Write the problems one by one on your hand or inner arm to keep practicing. There is also an electronic game called "Flashmaster" that works like flashcards and gives you a score. It costs about $50.00. Keep working at them and remember everybody learns differently; I have one daughter who is a whiz at math but can't do history and another who is great at history and reading but can't learn the times table for anything! P.S.- I graduated college and am a professional and I still don't know all of mine-(shhhh)

I am sooooooo proud of you that you actually want to learn something that, in spite of the old calculator, can never take the place of doing that quick calc in your head.
Look, just make a chant out of it... One times one is one.... one times two is two.. then.... nine times one is nine, nine times two is 18 nine times three 27, nine times four is 36.......... I learned how to do it this way in kindergarten and by the time I was five I had the whole kit and kaboodle down pat. Be patient, don't worry about being a slowpoke starter, just do it. It works. PS, I can also say the alphabet back'ards a s fast as I can forwards. That's a fun party trick to learn too because almost nobody can.

Do you like music? Find a song and start rapping or singing the times tables along with the song...find a rhythm...music is a wonderful memorization tool.
PS... you are NOT dumb!

I'm not a smart man. There is a multiplication "rap" song I heard when i was in grade school. It's corny and strange but it gets them stuck in your head.
