What are the Rules of adding and subtracting dissimilar fractions?
If their denominators are different then find their lowest common denominator by means of their lowest common multiple remembering to adjust their numerators accordingly before adding or subtracting.
What are the rules in subtracting similar fraction?
If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).
What are the rules for subtracting fractions?
You multiply the fractions until the denominators are equal. Then, you subtract.

What are the rules of subtracting polynomials?
You subtract a polynomial by adding its additive inverse. For example, subtracting (x - y) is the same as adding (-x + y). Alternately, you can simply subtract similar terms - that is, subtract the coefficients (the numbers) for terms that have the same combination of variables.
How are adding subtracting decimals different from multiplying them?
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
Why do you change mixed numbers to improper fractions before multiplying and dividing?
Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.
Rules in adding or subtracting scientific notation?
- when adding or subtracting in scientific notation, you must express the numbers as the same power of 10. This will often involve changing the decimal place of the coefficient.
