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.

Check out the following four playlist in order. These are made for people who don’t know how to add or subtract and it even explains the decimal number system.

I hope this helped. It helped me to learn other stuff. Of course you can start from a more advanced playlist if you feel you already know one of them.

    Working through the exercises on the Khan academy knowledge map is a fun way to practice.2014-08-14

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.
