Numbers that are in scientific notation that have a negative exponent are?
Exponents are negative numbers. This is used in math a lot.
Can every number be written in scientific notation?
Yes, except for zero. Numbers larger than 1 have positive exponents, and numbers between 0 and 1 have negative exponents. Negative numbers would just have a '-' in front.
What is the difference between scientific notation and negative exponents?
Scientific notation is a way to express very large or very small numbers. For very large exponent is positive; for very small exponent is negative. For example, 1,000,000 is 1 x 10 to the plus 6 exponent; 0.000001 is 1 x 10 to the negative 6 exponent
What are real life uses of exponents?
Scientific notation is a way to write very large or very small numbers using exponents. For example 2000 is 2x103 . We can do the same thing with negative exponents and write very small numbers like 1/2000 which is 2x10-3 . So one real life use of exponents in in scientific notation.
When adding or subtracting numbers written in scientific notation the exponents must be the?
Same.

Why do exponents need to be the same when using scientific notation?
Only if the numbers to be converted into scientific notation are the same otherwise the exponents can vary according to the size the numbers.

When subtracting numbers in scientific notation what you do with exponents?
yes its really important
When adding or subtracting numbers written in scientific notation the exponents must be the?
Same.
When dividing numbers in scientific notation what do you do with the exponents?
You subtract the exponent of the divisor from that of the dividend.
How can you express negative numbers in scientific notation?
Write the mantissa as a negative number.
When you add number in scientific notation the exponents are what?
When you add numbers in scientific notation, it is best to convert them to their original decimal form, or at least change them so that they have the same exponent. Then when you are finished adding, simply put the solution is proper scientific notation.
What is scientific notation and how do you use it?
Scientific notation is the use of exponents to indicate large numbers; for example, the number 25,000,000 can also be written in the form 2.5 x 107
How do you write 10.4 in scientific notation?
It took me forever to learn scientific notation because of how the exponents seem backwards. When you move the decimal to the left (towards the negative numbers in a line) your exponent will be positive. When you move the decimal to the right (towards the positive numbers in line) your exponent will be negative. So since we need a number between 1-9 in order have scientific notation we have to move our decimal one place to the left. 10.4 -> 1.04 x 101
