Maths are numbers games!
Knowing how to read and
write numbers fluently is enough to do mathematics calculations effectively.
If you can memorize
multiplication tables and have them at your fingertips, you'll be a whiz at
math.
Then memorizing
mathematical concepts and formulas and delving into its deep processes will
become your favorite pastime.
Take the square numbers.
That's the multiplication table you learned. In the second table, doesn't the
multiplication result of multiplying two by two come? In the third table, the
multiplication result of multiplying three by three comes, doesn't it? In the
fourth table, the product of multiplying four by four comes, doesn't it?
Similarly, in the fifth table, in the sixth table, multiplying a number by the
same number gives the result of multiplication, doesn't it? The product of that
multiplication is the square number.
Now you are able to
take the meaning of square number and its process from the context you studied.
Now tell me what is
square? A square is the result of multiplying the same number twice. The square
root is the return to its previous state. When the square is written as the
product of two numbers with the condition that it and the two numbers must be
the same number, that number is its square root.
Would you consider
writing a number as its product? A better method is to prime factorization. If
you want to find the square root of any square number, just factor that as
prime numbers. From that you can find the square root by taking a number for each
pair of prime numbers and multiplying them.
Long division method is
also useful for finding the square root of big square numbers.
Knowing square and
square root, you can easily understand cube number and cube root.
Multiplication of the
same number three times gives cube number. All you have to do is factorize the
number to find its cube root. You can find the cube root of a cube number, you
have to find factorization of that number as primes and take one number per
three same numbers and then you have to multiply the selected numbers. That is,
it is like selecting only one element from a group of three elements.
By now you understand
that fluency in numbers and memorizing the multiplication table at your
fingertips is essential for all of these.
Tomorrow we will see
how the games contained in this square and cube form theorems in mathematics.
