Yes
That's the "square" of the number. With counting numbers, the square will always be another counting number.

when you subtract one square number with another the answer is 16 what are the two numbers
4 and 9
The square numbers are: 16-4 = 12
No, the square of a number is not always larger than the number itself. For positive numbers greater than 1, the square will be larger. However, for numbers between 0 and 1, the square is smaller, and for negative numbers, the square is always positive while the original number is negative, making the square larger in that context as well. Specifically, zero squared is equal to zero.
Another square number.
The numbers are 9 and 25. (If you allow zero as a square 02 = 0, then 0 and 16 are another pair.)
16 and 4
1 and 36
No, and I can prove it: -- The product of two rational numbers is always a rational number. -- If the two numbers happen to be the same number, then it's the square root of their product. -- Remember ... the product of two rational numbers is always a rational number. -- So the square of a rational number is always a rational number. -- So the square root of an irrational number can't be a rational number (because its square would be rational etc.).
