But little things fail me like 1x0 = ?, I have always said 1. At the ripe age of 45 I now know it is 0. Is that not stunningly stupid? Seriously.
No not stupid. It means you don't understand multiplication, which means you were either not taught it, or taught it badly.
The Romans built an empire without a 0. Zero is an odd concept, it's not an actual number, it's the absence of a number, but is used in calculations as a number.
I've taught GCSE maths and I've tutored as well. The GCSE class was all mature students and if I ad a penny for every time someone said "Ah that's what that means", or "why didn't anyone tell me that at school".
I do understand the dyscalcula, I'm dyslexic so I understnad struggling when other people find it easy.
I also think if you are not a natural maths type then sitting looking at a board is not the best way to learn.
Eg 2 x 0 =
Just written down does not mean much if you don't understand the concept. But if I said "hold out your hand, ok you have nothing in your hand, now hold out your other hand, that has nothing in it either, so how much nothing have you got all together?"
OK, OP do you have any squared paper? Do you want to see if you can do maths?
if you do draw some random squares - the only rule is that you have to follow the lines on the paper, so you might draww round a single square, you might draw a square that takes up half the page. It doesn't matter how big or small as long as they are square and on the lines on the paper. This would be easier to show you.
Now pick 4 squares you have drawn.
count how many small squares are in the first one, write that number down, then count the number of squares on one side and write that down nest to the first number.
Do the same with the other three squares. write the numbers under the first ones, so you end up with two columns, one of larger numbers and one of smaller.
OK now get a calculator, put the first big number in and press the square root key - the answer should be the same small number you wrote at the side of it.
Try it with the others.
Do you know what this means? It means you worked out the square root of numbers without a calculator. How impressive is that.
