Arithmetic, Mental Math and Unit Conversion
Drill the four operations, percentages, shapes, time, length and weight.
Working out change in your head, calculating a discount while shopping, converting between units on the fly. Why not sharpen up the everyday arithmetic that makes life easier, with a few four-choice questions?
Take the basics quizWhat does it cover?
It covers the basics of arithmetic broadly: the four operations, percentages, shapes, and converting units of time, length and weight. It works equally well as a full review of primary school material, as a mental workout for adults, or as a way back into study. It is also a good one to work through together with your children.
What you will learn here
You will naturally build accuracy, speed and a feel for quantities. That becomes the foundation for being good with numbers in all sorts of daily situations — shopping, managing household finances, scaling a recipe — and it helps with estimates and rough calculations at work too.
How to approach it
Start with what you are good at, then use your accuracy rate to fill in the weaker topics bit by bit. Keep at it a little each day and your mental arithmetic will steadily get faster. The questions you get wrong are the ones worth the most.
