Explain, in words, how you solve the problem 232four + 123four with base blocks.
I start by drawing 2 flats 3 longs and 2 units to represent 232four then I draw 1 flat 2 longs and 3 units to represent 123four. In base 4 we make a trade when we have 4 of the same block. I take 4 units and make a long and I am left with 1 unit. I then take 4 longs and change them to a flat and have 2 longs left. I then take 4 flats and change them into a cube. I then count up what I have left: 1 cube, 0 flats, 2 longs and 1 unit. This is 1021four.
