How are adding and subtracting fractions similar?
Subtracting a fraction is the same as adding its negative.
How many more is subtracting or adding?
subtracting
Is sum adding or subtracting?
adding
What did you learn from adding and subtracting fractions?
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
How would you find the LCD when adding or subtracting rational expressions with different denominators?
No

How is doing operations with rational expressions similar or different from doing equations with fractions and how can they be used in real life?
How is doing operations (adding, subtracting, multiplying, and dividing) with rational expressions similar to or different from doing operations with fractions?If you know how to do arithmetic with rational numbers you will understand the arithmetic with rational functions! Doing operations (adding, subtracting, multiplying, and dividing) is very similar. When you areadding or subtracting they both require a common denominator. When multiplying or dividing it works the same for instance reducing by factoring. Operations on rational expressions is similar to doing operations on fractions. You have to come up with a common denominator in order to add or subtract. To multiply the numerators and denominators separated. In division you flip the second fraction and multiply. The difference is that rational expressions can have variable letters and powers in them.

In order to subtract two rational expressions by simply subtracting their numerators you must make sure that their denominators are equal.
What do you need to be careful of when subtracting rational expressions?
see the signs if is negative or possitive
When subtracting rational expressions with a common denominator always remember to the negative sign?
Distribute
What do you subtract when you have two rational expressions that have a common denominator?
When subtracting you have to make sure that the second numerator is multiplied by -1 so the equation turns into adding. When you add and you already have a common denominator you add the numerators and leave the denominator the same.
If the equation of a function is a rational expressions the function is rational?
Yes. Rational functions must contain rational expressions in order to be rational.
