The numbers up to 100 that are perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100. A perfect square is a number that is the result of a smaller number multiplied by itself.Know More
Square numbers follow the form n^2, where "n" is a whole number. This is the same as n x n. With a given number that is a perfect square, you can find the next number that is a perfect square. For example, if you are given the number 16, which has a root of four, you can add four and five to get nine and add this to 16. This equals 25, which is a perfect square of root five. One important point is that a perfect square can not be negative. Taking the root of a negative number would lead to an imaginary number.
The history of square roots dates back to the ancient Egyptians. While the exact methodology of how these individuals arrived at finding these numbers isn't known, one conjecture is that they used a right angle with two equal arms. The two arms were multiplied and a perfect square was produced. A second right angle would produce a square.Learn more about Numbers
There is some dispute as to whether zero is a perfect square. It meets most definitions of a perfect square, namely that it is an integer squared. However, it does not meet the historical definition of a perfect square, which involves arranging objects in a square shape.Full Answer >
All prime numbers are odd except for the number two. A prime number is defined as any whole number greater than one that has no positive divisors except for one and itself. Since two can only be divided by the numbers one and two, it is prime.Full Answer >
The property refers to how the opposite of a sum of real numbers is equal to the sum of the real numbers' opposites. The property written out is -(a+b)=(-a)+(-b).Full Answer >
Prime numbers are important in mathematics because they function as indivisible units and serve as the foundation of several mathematical disciplines. Because a prime number is a natural number greater than 1 that can only be divided by itself and 1, all non-prime numbers, which are called composite numbers, can be factored into a unique set of prime numbers. Computer security programs and cryptology are two fields that have made use of prime numbers to code and decode sensitive information.Full Answer >
