3. (a) Is like the 9 times table. 9, 18, 27, ....<br />
going down by 1 in the units and up by 1 in the 10s.<br />
(b) The last figures of the squares are 1 4 0 717 0 4 1 in base 9. In<br />
base 10 they are 1 4 9 6 $ 6 9 4 1. Both patterns are<br />
symmetrical.<br />
(c) The 3 times table, base 9 is like the 5 times table in base 10<br />
with a repeating simple pattern.<br />
