####Base-16 or Hexadecimal Blocks for Number Sense
The base-16 or hexadecimal (**numeral**) system is routinely used in computer science for convenience. Sixteen symbols are used: 0, 1, 2, ..., 9, A, B, C, D, E, F, where F(hex)=15(decimal)=1111(binary).
The 16-cube is getting too big. But still it is fun, at least, visually, to see the meaning of 1 in a number (or rather *numeral*) such as 1000(H). Even though the unit cube is 8mm^3 and the 16-cube is 124mm^3, it takes about 100 hours,
