Hello people

Im new to this forum, I hope Ive posted this in the correct section, I did search for help on my question before posting a new thread but didnt find speciffically what I was looking for.

I am very poor at maths, and over the next few weeks I will be doing a basic Maths course aimed at improving basic maths skills for those with little or none, like myself.

I am currently trying to learn some very basic things including Subtraction, Multiplication and Division. Today I am trying to learn how to subtract on paper. Borrowing and carrying over (I think thats what its called lol).

Sometimes it works other times it does not.

Heres a problem Ive given myself

23002

- 9439

The answer is 13563, using calculator, but when I try to do it on paper I get 11637

23002

- 9439

Basically borrow 1 each time from 3 (in 23002) to turn 2 (of 23002) into 12.

I'm struggling to even explain this so Ive made a picture, bellow.

Any help would be very much appreciated. If Ive over complicated it, Basically Id appreciate if you could tell me how to subtract that number (and others) on paper. Using borrowing numbers.

Thank you very much

Ross.
