Here are some cool math tricks and discoveries
I have learned over the years.

1) If you are multiplying any number of whole
numbers together, you will always gain an even answer if you have at least one
even number in the multiplication.

2) To quickly multiply any two-digit number by
11, simply add the digits up and put the result in between the original two
digits. This is your answer. If the result of the addition gives a greater
number than 9, then place the digit in the oneâ€™s place in the middle of the two
original digits, and carry the other digit and add it to the digit in the tenâ€™s
place.

3) A number is divisible by 9 if you can do
the following: First add each digit together, and then add the digits of the
result together. If you get an answer of 9, then the number is divisible by
9.

4) Can you explain why anything divided by 0
is undefined? Well, remember that division is just repeated subtraction,
X/Y means how many times can I subtract Y from X until I reach 0. Therefore,
when doing X / 0, I can subtract an infinite number of 0's from X and I still
wouldn't get an answer of 0. The term undefined also has to do with limits, but
thatâ€™s for a later discussion.

Below are what I consider two of the most
important things you can do to strengthen your math skills.

1) Don't do the homework problems until you do
some practice problems. If you have a textbook, re-read the chapter and do
those practice problems. You will no doubt learn some important technique that
will save you frustration down the line.

2) It all boils down to algebra. No matter the
upper level math course you take, algebra will nearly always be necessary.
Often times, the concepts aren't very difficult to understand. Yet students
always get the wrong answer because they can't understand the algebra, whether
it be exponent rules or factoring. As my calculus teacher put it, "Nobody
fails calculus because calculus is hard. They fail because they suck at
algebra."

Practice as much as you can, connect the dots, see the patterns and make life easier for yourself. The reason many people hate it is because they don't properly understand it. Once you do however, you see why it can be fun.
