"I thought I'd done it"

I've sent quite a few people's MSE homework back. Please make sure you explain your method. I'm pretty sure I've explained this about 1 million times, so don't be offended.

Just in case you really have perfected the art of sleeping with your eyes open, here is the explanation again.

For example, when I ask you to show me how to "Multiply by 20", typing 23x20= 460 is not enough. You need to say- double 23 and multiply by 10.

I'm interested in the recipe and not the cake.

EXPLAIN YOUR METHOD!

If you've had your MSE sent back, have another look, spend a bit more time and get it right. I'll be giving you a score.

As always- enjoy.
