Timeout for a Martin Gardner puzzleWith my 10 year-old VN student today we took a break from Physics and Chemistry (vector diagrams with billiard balls was a bit too heavy and the webwhiteboard app was pretty awful) to look at one of Martin Gardner's simpler problems:
G O O D
+ T I M E
M A T H S
The ten letters each being different letters.
No leading zeroes of course, and there are several answers.
Care to try your hand at it? Note that D and E are interchangeable but we don't care.
What is the number represented by MATHS? Can you find more than one solution?
