Now what value does this setting below represent?
Answers
Note: To subtract the 305 from 822 (the examples above), we first subtracted
three 100 unit beads by pulling them away from the center, then we attempted
to take away one 5 unit bead, but there were no 5 unit beads available,
so we temporarily subtracted one 10 unit bead and added two 5 unit beads
to compensate for this temporary condition. We were then able to subtract
the one 5 unit bead to finish up our calculation. After this work, we simple
read the answer from left to right.
