Math is not as hard as people think it too be. Currently I am taking Calculus 2, Yes it's bullshit hard but it all makes sense.
In order to understand math you need to understand more and more basic concepts. For instance your first example may look completely daunting at first.
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6 ) = 7x + 21
but it's actually very simple.
x + x = 2x because, if x = 2,
(2) + (2) = 2(2)
2 + 2 = 4 or 4 = 4
there for the equation above can be rewritten as
x+x+x+x+x+x+x+1+2+3+4+5+6 = 7x + 21
1+2+3+4+5+6 = 21
and there are 7 x's so these 7 x's combine to 7x same as
x+x+x = 3x
x+x+x+x = 4x
There for 7x + 21 = 7x + 21
just brush up on simpler concepts and to be honest a great study resource is Youtube. There are plenty of videos about all different subject in math there. Don't listen to anyone who says you don't need math... you do need math, all of it. It's up to decide when you want to stop learning because you can never stop learning new things.
