The first 10 positive cube numbers are: 1, 8, 27, 64, 125, 216, 343, 512, 729 and 1,000. These are the cubes for the numbers one through 10. Zero, which is neither a positive or a negative number, is the cube of zero.
Know MoreCube numbers are the product of an integer multiplied by itself, and then by itself again. A cube number is the product of a base number, n, to the third power, written exponentially as n^3. For example, 4 x 4 x 4, or 4^3, yields the cube 64. All positive numbers raised to the third power have positive cubes. Negative numbers raised to the third power, however, have negative cubes. Two negative numbers multiplied together have a positive product, but when that product is multiplied by the negative number again, the answer is negative. For example, -4 x -4 x -4, or -4^3, equals -64.
It is not possible to name the very first 10 cubes, because negative numbers are infinite. There is, therefore, no smallest cube. In the number sequence that includes odd integers beginning with one, the first number, one, is a cube. Adding the next two numbers, three and five, yields the second cube, which is eight. The sum of the next three numbers in the sequence, seven, nine and 11, is the next cube, 27. The pattern continues.

Full Answer >Negative numbers are real numbers. The set of real numbers includes all the numbers that can be shown on a number line including both positive and negative numbers.
Full Answer >Two numbers are relatively prime if they have no common divisors other than 1 or -1. It is not possible to divide both numbers by a common value to produce a whole number.
Full Answer >To round numbers, decide on the place to which to round. Round up if the digit itself or the digit to its right is five or greater, and round down if the number is less than five. Rounding a number means to reduce its digits while keeping the value similar.
