Hi Elijay
I would say as far as addition, subtraction, multiplication, percentages and division is concerned I am good.
A little while ago I was asked about a mathematical formula I had not used since school.
The child left it with me for about 30 minutes and I worked it out.
I left school 45 years ago so I do not think that is bad.
My mother in law who was the headmistress of the school I went to thought I was better than her in this respect. She mainly taught foreign languages where as I was more on the business studies side so I suppose I was closer to maths.
