1) Think of a two digit number
2) Multiply it successively by 3, 7, 13, and 37
3) What is the result?

For example you r two digit number is 97.

```   97 x 3  = 291
291 x 7  = 2037
2037 x 13 = 26481
26481 x 37 = 979797
```

It is the same two digit number repeated three times!

Why does it work?

Since 3 x 7 x 13 x 37 = 10101, then any two digit number ab x 10101 = ababab

```           ab	           59
x 10101	      x 10101
ab	           59
0	           0
ab  	         59
0	         0
ab    	       59
ababab          595959
```

That is Math, Simple and Cool!

There are parents who are allergic to Math and  who say MATH is an acronym for

Mental Abuse THumans

They conclude that just because they are allergic to math and are certified math-haters, they cannot teach math to their children.  And I’d tell them the first and most important MATH lesson you can teach your child is “Mathitude.”

Mathitude is the term I use to refer to the attitude to use in approaching Math (and many everyday) problems. Among the more important things that I taught my children are:

• Most problems can be solved.
Complex problems can usually be broken down into simpler parts which are more easily solved.
• Problems can have different solutions.
Obvious solutions may not be the best.
• You can develop shortcuts in problem solving, but do not take shortcut in education.
One must not only learn, but also master, the basic concepts. Each succeeding math course builds upon the previous courses. If they find the current lesson hard to understand, then they must review the previous lessons.
• The cliché “practice makes perfect” is especially true in Math.
Math is learned not just by reading but by also doing. I ask my children to solve every available exercise or problem about the current lesson.
• Teaching helps learning.
I ask them to teach their classmates or younger kids. You cannot teach what you don’t know.
• Try to solve problems first before asking for help.
Study lessons before they are discussed in class. This helps the children develop self-reliance. But don’t be afraid to ask questions if needed.
• Understand and not just memorize.
Math is best learned by understanding the basic concepts and not just memorizing the math facts and solution steps.
