Not just for kids. Quick what's 14×13? With four levels of exponential difficulty Tellcraft is for mathmos of all levels and abilities. Here's an easy way to solve multiplication problems of two digits:
1. Multiply the last two digits, i.e. 4×3 = 12. The last digit is the last digit (2) in the answer and the first digit is the carry (1).
2. Cross-multiply the bottom two digits with the top two digits and add them together with the carry, i.e. 3×1 + 4×1 + 1 = 3+4+1 = 8. (Since 8 less than 10 there is no carry in this step.)
3. Multiply the last two digits and add any carry from the last step, i.e. 1×1 = 1.
4. Gather the results from steps 1, 2, and 3; 2,8,1 => 182.
