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.
Write the mantissa as a negative 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
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.
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.
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.

No, if there is a negative number then you put that many numbers before the root number. For example, 7x10^-5= .000007

how to express scientific notation to a simle number
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.
first you put a decimal behind the first whole or non zero number then how ever many spacesyou moved is the positive or negative power of 10
they express the numbers using scientific notation
An example of a number in scientific notation would be 3.7 x 10⁶
2.37 X 102 ============as you see for numbers this small scientific notation is more inconvenient than just writing the number in standard notation
Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10^b where 1
