Use place shapes to examine identical quantities

across bases.

Quantity ten shown in five bases

146 = 137 = 12 8 = 119 = 10A  

Quantity hundred shown in three bases

144 8 = 1219 = 100A  

(8+2)2 = +1(8)2 +4(8)1 +4 = + 100 (9+1)2 = +1(9)2 +2(9)1 +1 = + 100 (10)2 = +1(A)2 +0(A)1 +0 = + 100

13319 = 1000A

Quantity one thousand shown in two bases

(9+1)3 = +1(9)3 +3(9)2 +3(9)1 +1 = + 1000 (10)3 = +1(A)3 +0(A)2 +0(A)1 +0 = + 1000

146419 = 10000A

146417 = 100008 (4,096)

Use place shapes to examine identical subQuans

across bases.
