   Here's a maths q for younger learners: my lunch needs 90 seconds at full power but my microwave only has buttons for 10 seconds, 1 minute, and 10 minutes. What should I press?
   Follow ups:
   What if there was also a button for half a minute - what combinations could I use then?
   If you could choose what times to put on the three buttons, what would you choose and why?

     Further ideas for older learners: the instructions are 90 seconds in a 900W microwave but mine is only 850W - what advice can you give me? (buy a new microwave is not an option!)
