Question

3.4 Which base -10 ( Dienes) blocks represent the sum of 1034 and 675?

Answer 1

1 cube = 10 falt;

1 flat = 10 rod;

1 rod = 10 unit.

1034 = 1 cube , 3 rod, 4 unit

675 = 6 flat , 7 rod , 5 unit

1034 + 675 = 1 cube, 6 flat, 10 rod, 9 unit

Since, 10 rod is equal to 1 flat, we express it as follows:

1 cube 7 flat 0 rod 9 unit = 1709

Answer:

1 cube, 7 flat, 9 unit
