Can some explain this please?!?

This was taken from another forum by the user name "KnOw YoUr RoOts".

and his lesson is..

You've all heard of chords more then likely, but what lots of people donâ??t know is how to find the chord, and how to find whether itâ??s major, minor, augmented, or diminished chord. 
 
 First to find the simple chord you find the 1st 3rd and 5th note in the scale
 for example we'll used C Major. This scale has no sharps or flats.
 
 C-D-E-F-G-A-B-C
 
 1|3|5 You can add other notes to the chord like a 7th 
 C|E|G or a 9th but we will get to that later.
 D|F|A
 E|G|B
 F|A|C
 G|B|D
 A|C|E
 B|D|F
 
 Now in-order to find out if it is a minor, major, diminished, or augmented chord. 
 
 What you do is you use the chromatic scale of C 
 
 C-C#-D-D#-E-F-F#-G-G#-A-A#-B 
 
 lets start with C-E-G . 
 Start at C as 1 then C3 as minor 2(m2) d as Major2 (M2) and so on till we reach E. 
 
 C - C# - D - D# - E - F - F# - G - G# - A - A# - B
 1 m2 M2 m3 M3 
 
 We have E as a major 3 
 
 We start again at E as 1 till we get to G doing what we did before
 
 C - C# - D - D# - E - F - F# - G - G# - A - A# - B
 1 m2 M2 m3
 
 We get G as m3. So we have A M3 and a m3
 
 Now like math chords have types of equations 
 Major= M3 and m3
 minor= m3 and M3 
 Diminished= m3 and m3
 Augmented= M3 and M3
 
 Using all that we've learned so far we can see that CEG having a M3 and a M3 is a major chord. try this system for all of the different chords on the chart that I showed you earlier. 
 
 
 You should end up getting the below
 
 
 1|3|5 
 C|E|G Major 
 D|F|A minor
 E|G|B minor
 F|A|C Major
 G|B|D Major
 A|C|E minor
 B|D|F Diminished
 
 
 you'll find the patterns after you practice a bit.
 
 
 
 
 Now I will talk about the 7ths and the 9ths that I mentioned earlier
 
 
 You remember the chart I showed you earlier, weâ??re going to use that and use that same scale.
 C-D-E-F-G-A-B-C
 
 1|3|5|7 See how I have added another space to the chart.
 C|E|G|B I've added room for the 7th note of the scale. This
 D|F|A|C give the chord a different sound as you can hear 
 E|G|B|D when you play it. It adds more color to the chord.
 F|A|C|E It's simple to find the 7th note you just go up to
 G|B|D|F the 7th note for C it is CEGB. You can do the same 
 A|C|E|G for the 9th 
 B|D|F|A
 
 
 You can use this for scales of all kinds such as harmonic minor, natural minor or many others.
 
 I hope this helped you out if you need anything else just ask

My question is can some explain this better?

this part " Start at C as 1 then C3 as minor 2(m2) d as Major2 (M2) and so on till we reach E. "

thanks

Typo.

Start with C as 1, then C# as minor 2nd (m2), and D as major 2nd (M2) and so on till you reach E. Not telling you much you don't already know.

thanks jender would have never though of it that way
