The last digit in any number is referred to as the estimated digit. In science, all other numbers are considered significant digits because they are precise measurements.
Know MoreThe last number in a measurement in science is simply an estimation. For example, if a metal rod measures slightly over 234 inches, the final measurement can be rounded so the answer is 234 instead of 234.2. The more significant numbers a digit has, the more precise the measurement. A significant number includes all non-zero numbers, all zeros that fall between two significant digits and all zeros that are to the right of a decimal point or to the right of a non-zero number.

Full Answer >The number one is neither prime nor composite. Prime numbers are positive integers greater than one that are evenly divisible only by themselves and one. Composite numbers are positive integers that have divisors other than themselves and one.
Full Answer >A number that is multiplied by itself is called a base when it is written in exponential notation. Exponential notation consists of the number to be multiplied and a numeral in superscript to the right of it to indicate the number of times it is to be multiplied by itself.
Full Answer >The number one is neither prime nor composite. Prime numbers are those defined as natural numbers greater than one not divisible by any other numbers but one and itself. Composite numbers have at least one additional positive divisor and include all whole numbers greater than one that are not prime.
