To add or subtract numbers in scientific notation you first need to equalise their exponents. Having done that, you carry out the addition or subtraction on the significands and append the common exponent. Then you adjust the exponent so that the significand is between 1 and 10.
For example,
1.234*104 - 2.34*102
(equalise exponents) = 123.4*102 - 2.34*102
(carry out subtraction) = (123.4-2.34)*102 = 121.06*102
(adjust exponent) = 1.2106*104

How do scientists write very large numbers?
they express the numbers using scientific notation
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.
A method of writing very large or very small numbers by using the powers of 10?
It is scientific notation or standard form
Write the number 376000000000 in the scientific notation format as well as the regular format In addition explain any other advantages of using scientific notation?
376000000000 in scientific notation is 3.76 × 1011Standard notation is 376,000,000,000Scientific notation (also called standard form or exponential notation) is a way of writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.
What is the measurement of 0.000.004.3 m using scientific notation?
0,000,004.3 in Scientific Notation = 4.3E-06 x 106
What is the disadvantage of using scientific notation?
If you are adding or subtracting two numbers in scientific notation, you must rewrite one of the numbers to the same power of ten as the other, before performing the addition (or subtraction).
What is the point of using scientific notation?
The point of using scientific notation is to compute very large or very small numbers.
What is the purpose for using scientific notation in scientific?
Using scientific notation reduces the need to write out very large or very small numbers as the following examples show:- 1,000,000,000,000 = 1.0*1012 in scientific notation 0.0000000001 = 1.0*10-10 in scientific notation

What is a method of writing very large or very small numbers by using powers of 10?
scientific notation
When you abbreviate very large or very small numbers you are using?
scientific notation.
When you abbreviate very large or vary small numbers you are using?
scientific notation
Writing numbers in standard form with decimals and powers?
It is using the scientific notation.
When is expressing using scientific notation useful?
When numbers are tremendously large or small.
Is exponential notation the same as scientific notation?
No. 35 is exponential notation, (3 is the base of the exponent 5), but in scientific notation the base must be 10 and the exponent must be an integer. 100.1 is exponential notation but not sci. notation.
What are the practical uses of scientific notation?
The practical uses of scientific notation are to compute very large or very small numbers.
