This week we learned about adding and subtracting rational fractions. This skill was a little trickier than multiplying and dividing. When subtracting I would usually change the signs of each value in the second numerator so that every question would be addition. Then I would find a common denominator of the two equations. I would multiply the numerator by what is missing in the denominator. This would simplify the equation and when solving, get rid of the denominator. Then I can simplify the coefficient.
