Add & Subtract Scientific Notation

Front

What does a negative exponent indicate about a number?

Back

A negative exponent indicates that the original number was a really small number.

Front

How do you add numbers in scientific notation?

Back

To add numbers in scientific notation, you must first ensure they have the same exponent. If they don't, adjust one of the numbers so that both have the same exponent, then add the coefficients.

Convert 0.0005 to scientific notation.

Back

0.0005 in scientific notation is 5 x 10^(-4).

Front

What is the result of (2.8 x 10^8) + (5.4 x 10^9)?

Back

The result is 5.68 x 10^9.

Front

What is the result of (2.3 x 10^2) + (4.1 x 10^2)?

Back

The result is 6.4 x 10^2.

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, using powers of ten.

Front

How do you convert a number to scientific notation?

Back

To convert a number to scientific notation, move the decimal point in the number until only one non-zero digit remains to its left, and count the number of places moved. This count becomes the exponent of ten.

Front

What is the coefficient in scientific notation?

Back

The coefficient in scientific notation is the number that is multiplied by the power of ten, typically a number between 1 and 10.

Front

What is the purpose of scientific notation?

Back

The purpose of scientific notation is to simplify the representation of very large or very small numbers, making them easier to read and work with.

Front

How do you subtract numbers in scientific notation?

Back

To subtract numbers in scientific notation, ensure they have the same exponent, adjust if necessary, then subtract the coefficients.
