Scientific Notation

Front

What is scientific notation?

Back

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It is typically in the form of a x 10^n, where 1 ≤ a < 10 and n is an integer.

Front

What does the exponent in scientific notation indicate?

Back

The exponent indicates the power of 10 by which the coefficient (the number in front) is multiplied. A positive exponent means the number is large, while a negative exponent means the number is small.

What is the range of the coefficient in scientific notation?

Back

The coefficient must be greater than or equal to 1 and less than 10.

Front

How do you determine which of two numbers in scientific notation is larger?

Back

Compare the exponents first; the number with the larger exponent is greater. If the exponents are the same, compare the coefficients.
