TITLE: Tips for an adult to learn math -- from the beginning.
QUESTION [16 upvotes]: First let me start with I am an adult and I can't do simple maths. I some how got through all of my math courses in University (after several attempts) but I honestly couldn't tell you how...
I cannot do these:

Add/Subtract with decimals
Add/Subtract fractions
Basic multiplication 
Basic division
More advanced math that uses these principles

How can I go about learning these things now? Is there a particular book that I can study from (with worksheets). I'd really rather not do exercises that involve connecting dots to create pictures, or coloring things...
As a side note, I believe I suffer from dyscalculia.

REPLY [2 votes]: Thinking Blocks is a great resource for understanding ratios and proportions.(And it also has addition and subtraction.  It's very interactive. It guides you one step at a time, and gives you feedback every step, so you know if your thinking is correct.  You don't have to wait until the end of the problem to find out.
