Remember: Take away the tens and the ones, row by row. Each row works on its own when it has enough beads.
Read and answer
Read the story, then answer.
The bead stallIt was market day, and Ben had a bead stall. Under the counter sat a box with 86 beads in it: eight bundles of ten and six loose ones. On the frame the top row showed eight tens and the bottom row showed six ones. A shopper asked for 24 beads, which is two bundles and four loose ones. Ben took away two tens, so eight tens became six. Then he took away four ones, so six ones became two. The ones row never touches the tens row, because each row works alone. Six tens and two ones is 62.
