All numbers are octal, and colored regions show several numbers º1-º14 can multiply to that same number.

May this chart come in useful (and maybe even mentally faster than the calculator, too)

...and I'm finally back with a division chart for fractions:

How it works: the numbers in the light boxes are formed by dividing the number in the first row (dark boxes) by the number in the first column (dark boxes).  All fractions are in their reduced form, and improper fractions are used to save space.  Equivalents aren't colored this time, hìtxoa.

May this chart be as useful as the first
