Which base-10 (Dienes) blocks represent the sum of 1034 and 675?
1Cube=10square
1square= 10column
1column= 10dot
1034= one cube, zero square, three column and four dot.
675= six square, seven column and five dot.
now we count how many cubes, how many squares, how many columns and how many points in total:
1034+675= one cube, six square, ten column (or one square) and nine dot.
That's, one cube, seven square, zero column and nine dot = 1709
ANSWER: 1709
