There is none. Numbers don't stop. You can always add another zero.
When you subtract one number from another you get the difference.You just said it; sum.
The two square numbers that add up to 225 are 144+81 = 225
There are infinitely many possible answers. The smallest set of numbers is (9, 16, 144, 169)
the answer is for example 9+16=25=square number

Square numbers.
That probably means that you are supposed to add them.
the two numbers in the circles add up to the number in the square box!
The square of the second number.
generally you would multiply a number by itself, but i have found out a marvelous trick, and it is pretty easy since I am only a child, but starting with 1, if you add three, you get four, the next square number. then you add five to get nine the next square number, then seven to get sixteen and so on. So in simpler terms you take one and add three to get the next square number, then add five, then seven counting by odd numbers. Here is an equation. the bold numbers are the square numbers and the Italic numbers are the progressing odd numbers.1+3= 4+5= 9+7=16and so on.
The numbers you add together are called addends. If you add one number to another to form a sum, the number you add on can be called the augend. See the Penguin Dictionary of Mathematics.
If you add an even number to an even number, you will have an even number as a result.
Another rational number.
