How do you add two negative scientific notation numbers and come out with a negative scientific notation number?
StefanG96
Ignore the scientific notation part for now. How do you add two negative numbers and get a negative number? That should be obvious: for instance, -7 + -3 = -10. You need to add a positive number greater than the absolute value of the negative number to make a positive number.
Now, put in the idea of scientific notation. It really is just bookkeeping of decimal places so you don't have to keep writing them all out. It is still the same idea! If you doubt this, just expand it out and see how it works. For instance,
-3 x 10 ^ 3 = -3000
Add in another negative number in scientific notation, say -6 x 10 ^ 4 = -60000. What do you get when you add them?
-3000 + -60000 = -63000, or -6.3 x 10 ^4.
If scientific notation ever confuses you, just expand it out and remember what it really is doing for you- it just collapses a bunch of digits you don't want to keep writing.

How can you express negative numbers in scientific notation?
Write the mantissa as a negative number.
How do you subtract two negative scientific notation numbers and come out with a negative scientific notation number?
if the smaller negative sci notation # being subtracted from the larger example: (-1.0x10^0) - (-2.0x10^0) is the same as -1-(-2)= -1 + 2 = 1
Can a negative number be expressed in scientific notation?
Yes, a negative number can be expressed in scientific notation. In scientific notation, a negative number is indicated by the negative sign (-) placed before the first significant digit. The number is then written in the form of a decimal number between 1 and 10, multiplied by a power of 10. For example, -3.2 x 10^-5 is a negative number expressed in scientific notation.
What is the scietific notation of this number 0.000000048?
Scientific notation is a math term you learn in school. It is used to abbreviate large numbers. 0.000000048 written in scientific notation is 48x10 to the negative 8th power.
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.

When a number written in scientific notation includes a negative exponent is the number negative?
No, if there is a negative number then you put that many numbers before the root number. For example, 7x10^-5= .000007
