Simplify 8/(7v-6)+4/3v^2. We learn how to simplify 8/(7v-6)+4/3v^2 in this free online math video lesson on Adding and Subtracting Rational Expressions. This video explains how to add a rational expression and how to subtract a rational expression and simplify each expression. We have to find a common denominator before we add or subtract the rational expression 8/(7v-6)+4/3v^2. #addingrationalexpressions #subtractingrationalexpressions #minutemath
Hey everyone! In this video, I'm going to show you the Butterfly Method for adding fractions. This method is a great way to add fractions if you don't want to use the traditional method of finding the common denominator. The Butterfly Method is easy to use and makes adding fractions simple. So let's get started!
First, you'll need to find the two fractions you want to add. Then, draw a butterfly shape on a piece of paper. Place the two fractions on the wings of the butterfly and draw a line connecting them. Now the denominators of the two fractions should match.
Next, multiply the first fraction's numerator by the second fraction's denominator. Also, multiply the first fraction's denominator by the second fraction's numerator. Then adding these two numbers together will be the answers numerator.
Next, multiply the two fractions' denominators to get the denominator of the answer.
Finally, write the fraction with the new numerator and denominator and you have the answer!
That's it for the Butterfly Method for adding fractions. Give it a try and see how easy it is! Thanks for watching and good luck!

In this video we learn how to Calculate the median of a set of numbers. We find the mean of the numbers 12, 13, 19, 9, 11, 15, and 18.
The steps we followed to find the median of a set of numbers is:
1) List the numbers from smallest to largest.
2) Count how many numbers are in the set. Call this n.
3) Is n even or odd?
3a) If n is an odd number, the median is the middle value.
3b) If n is an even number, the median is the mean of the two middle values.

In this video we learn how to determine if a number is prime. We determine if the numbers 83 and 77 are prime or composite.
The steps for determining if a number is prime are as follows:
1. Test each of the primes, in order, to see if it is a factor of the number.
2. Start with 2 and stop when the quotient is smaller than the divisor or when a prime factor is found.
3. If the number has a prime factor, then it is a composite number. If it has no prime factors, then the number is prime.
