Having the ability to do basic mental arithmetic is a valuable skill we use every day. Being able to make reasonable estimates can save you from making potentially expensive mistakes.
What's 23.71 x 42,372? No idea, but having a feel for numbers and mental calculations allows me to work out straight away that the answer is going to be somewhere near 1,000,000. If I then input the numbers into a calculator and get an answer closer to 100,000 or 10,000,000, I know from my estimate that I've messed something up.
How would somebody with no grasp of estimating numbers detect that error? Now use the same logic with somebody trying to understand a terrible car-finance deal that a salesman is pushing at you, or any kind of loan or contract?
