Ms Tayke

Twenty three again?

Happy Birthday Ms Tayke!

Ms Tayke

Ms Tayke does not want anyone to know how old she is. We think she is 705 but she often subtracts 23 from her age to make her feel younger.
How many times can you subtract 23 from 705?

  • Well done 9AM, Southam College! Good answer. There are more smart answers to this question lower down this page. The countdown clock above is a distractor, it leads the pupils to think that they are being asked to do a time consuming activity whereas the most efficient strategy would be to a mathematical operation not mentioned in the question at all.
