Try thinking of different fraction types as different languages. The ones with the same number on the bottom are in th same language eg 3/7 and 5/7 and you can add & subtradt them. To change a fraction from one "language" into another you multiply top & bottom by a number. So 1/2 lets say is a word in English but if you multiply both top & bottom by 5 you get 5/10 which is the same "word" but in French. The fraction is the same size ie 1/2 = 5/10 but it's just written in a different language.

2 words MATH SUCKS!!!!!!!! u don't even need half of this stuff in life and my parents when they were growing up they didn't learn this and they made it through life just fine.

@Crazen14 - Many people believe this, although what sucks is that kids are forced to learn stuff without being given a good reason. Many students do need these basic skills in order to go on to very useful areas of study but you are quite right society requires some young people to jump through hoops and they may never go on to use the skill. These videos are just there for those who want a bit of help with it , and for those who don't - well I guess they don't have to watch.

PS

5/9 + 3/4 change both fractions to /36 First one multiply both top & bottom by 4. Second one multiply both by 9 . You should now have 20/36 + 27/36 add these together to get 47/36 since 36/36 is a whole one you have 1 & 11/36

do you have a video with the same concept, but more complex? I need help with adding fractions that need factoring and have variables.

[psychosides]

@squiddie96 sorry - these videos are aimed at basic arithmetic skills - I do plan to do a more advanced set of videos - probably algebra but cannot say when. There are however more advanced stuff already on the system - which is why i stuck to basic maths PS

@natethepain poop rocks

I love you for helping me with my math homework and why are the top comments so long :|

[EconMBAStudent]

Very clear teaching - looking at other videos explaining the same concept has made my head spin. This has restored my faith (confidence) in maths.

[missmochashake]

Thumbs up this method was precise and well understood.

@psychosides Dude im not joking thanks to you, I got 100 on my math test! i ussually get an 80-95's but i got 100 just for watching 1 simple video. THANKS ALOT KEEP IT UP!!
