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.

    Out of interest, what course did you take at university? – SiliconCelery Jul 31 '12 at 13:35

    Linear Algebra (I/II), Discrete Mathematics, Statistical Methods – 에이바 Jul 31 '12 at 13:49
  • That's interesting!! – Landon Carter Jan 24 '15 at 17:58
  • @6005 Would you please refrain from bumping this many years-old questions at once for the sake of a tag-edit? This pushes legitimate recent questions off the homepage. – Lord_Farin Aug 30 '15 at 08:50
  • @Lord_Farin My apologies. I'm trying to work towards the removal of the [tag:self-learning] tag, but I have only been doing it very occasionally, and in blocks of only 10-15 questions at a time. – Caleb Stanford Aug 30 '15 at 08:58
  • @6005 That sounds reasonable. The only advice I'd like to add is to monitor the homepage to make sure you don't exceed ~40% of the first view. One way I have done this in the past is by editing other questions on the homepage to improve their formatting or things like that, so they get bumped over your tag edits. – Lord_Farin Aug 30 '15 at 09:03
  • @Lord_Farin Thanks for the tip, I'll try that sometime. – Caleb Stanford Aug 30 '15 at 09:07
  • @6005: Why don't you contact the maintainers of MSE and ask them to replace one tag by the other (assuming you have a solid justification for this)? It would take them only a few seconds. – Alex M. Aug 30 '15 at 09:12
  • @ 에이바 Apart from the of arithmetic content, ambiance plays some part I think.Open ventilated places, working mornings after a good night sleep, and a bit of no-side effect natural homeopathic medication etc. would also help. – Narasimham Aug 30 '15 at 09:24
  • @AlexM. See my question on meta. – Caleb Stanford Aug 30 '15 at 09:26

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.

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.
