My maths is of an good standard, A at GCSE (uk exams at 16) but I find I still need to write down simple aritmetic on paper, before being able to work it out.
For example, questions I encounter day to day I cannot work out "on the spot mentally" or as quick as I would like, such as
Work out 8% of 17000.
The meal cost 0.97 for the drink and 1.85. I paid with £5, how much do I get back?
Quickly tell me what 15 multiplied by 12 is.
I can easily work these out given pen and paper quite quickly, but it's hopeless if Im not. However I notice a lot of people that didn't do that well at maths in exams, can work these sums out on the spot. What is their secret?
Is my brain wired differently?
Books or sites advice would be best.
