Remember we posted about bad maths costing us money, when it came to working out whether some of the deals we see in the shops were actually that good or not?
If you’re no Carol Vorderman and find yourself running out of fingers to count on or trying to locate the calculator function on your phone whilst doing your weekly big shop, it might be worth trying to improve your mental maths with the help of this growing list of tips.
The current tips won’t necessarily help you directly with your shopping, but the mental work out they give should help you, and should help you find other ways to quickly work with numbers.
This article on how to do maths in your head might also help, and you can test yourself with a few example sums. My biggest tip would be to break big numbers into sums that you can manage. For example, how would you divide 235 by 5?
If you start by dividing 200 by 5 you get 40, then divide the remaining 35 by 5 (7) and add that on. Hey presto. Or just whip out your phone and tap a couple of numbers in.
