Maths not my favourite word

I have a great problem with maths.  I don't know if a person can be dyslexic with figures but I seem to be.  I might be able to do a simple problem right the first time but then I think about it and do it again and end up with the wrong answer.  I am undertaking a numeracy subject at my Adult Campus and have to complete a work sheet with simple arithmetic problems. I am having a hard time working out rounding out numbers.  This should be extremely easy but I got lost along the way somehow and now have to stop for a period of time so that my brain re-sets itself.  When I was in high school I used to take two to three hours to do my maths homework and have every sum wrong.  I managed to top myself in year 10 when I received 14% in semester one and 11% in semester two for arithmetic, and this was after being coached for a semester to improve my score.  Ho hum!  I must just keep plodding along but from previous results I do not think that this will be my finest hour.  I would like to be able to say at the end of this semester veni vidi vici, I came I saw I conquered.  I think however, that my final result will say YOU FAIL AGAIN GRASSHOPPER!!!!!!!!!!!!!!!!!!!!!!
