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).
The point of using scientific notation is to compute very large or very small numbers.
111100002 equals 24010 using unsigned notation. It equals -1610 using signed notation.

Using power-of-notation makes it easy to multiply numbers.
Decimal notation is.
Numbers are either irrational (like the square root of 2 or pi) or rational (can be stated as a fraction using whole numbers). Irrational numbers are never rational.
It means that either the numbers involved in the word problem are all rational or that any irrational numbers are being approximated by rational numbers.
Yes, it is. Moreover, it is also a rational number. 1.25 * 4 = 5, so 1.25 = 5/4. All rational numbers are real numbers, so 1.25 is real. Any number you can think of, using decimal notation is real. Real numbers are allowed to have an infinity of digits (behind the decimal point).
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).
Yes, as long as the two nonzero numbers are themselves rational. (Since a rational number is any number that can be expressed as the quotient of two rational numbers, or any number that can be written as a fraction using only rational numbers.) If one of the nonzero numbers is not rational, the quotient will most likely be irrational.
The point of using scientific notation is to compute very large or very small numbers.
It is the distance from the origin to the number in question.
111100002 equals 24010 using unsigned notation. It equals -1610 using signed 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.
