When calculators get it terribly wrong! Can you explain this?
This is definitely an example of when calculators get it very wrong and would make a great starter for discussion and debate in any Maths lesson. It appears that one of the calculators has not been taught the order of operations, can you tell which one? : )
Can you explain why this is the case? The original tweet caused a twitter storm and generated some interesting discussions. Comments are free, please leave one below.
