Is it normal that i bring a calculator when going to a shop?
When I go to a shop, I usually go to a shop with my money and calculator the reason why I do it is because I want to work out how much I'm buying and the percentage of money being spent. Even though I still hate maths I make it a habit even though people stare at me in the shops while using a calculator.
Also I use it when finding out how much I can buy a product when I'm on a budget and also seeing if I'm exceeding the budget.
Is this habit normal?
