Solution - Operations with Numbers in Scientific Notation

Have you ever heard of the distance between the Earth and the Sun being about 93 million miles? That's a pretty big number to work with! But we can use scientific notation to make it easier. 93 million can be written as 9.3 x 10^7. That's a lot easier to write and work with!

Another example is working with really small things, like atoms. Did you know that there are about 602,000,000,000,000,000,000,000 atoms in a grain of sand? That's a huge number, but we can use scientific notation to make it more manageable. 602,000,000,000,000,000,000,000 can be written as 6.02 x 10^23.

Operations with numbers in scientific notation can also be helpful in science and engineering. When scientists or engineers are working with really big or really small numbers, it's important to be able to easily compare and manipulate them. For example, if a scientist is working with the distance between stars, they might need to add or subtract numbers that are in scientific notation. Or if an engineer is working with really small parts, they might need to multiply or divide numbers in scientific notation to get the right measurements.

Overall, learning operations with numbers in scientific notation can make working with really big or really small numbers much easier and more manageable. It's a really useful tool to have in your toolbox, and can be helpful in a wide variety of fields, from science and engineering to astronomy and beyond!
