<human>:  A wood stove burns 4 bundles of wood in the morning, then some more in the afternoon. If there were 10 bundles of wood at the start of the day and 3 bundles of wood at the end of the day, how many bundles of wood were burned in the afternoon?
<bot>: How many bundles of wood were burned throughout the day? ** Working out the difference between the amount of wood available at the start and the end of the day shows that 10 bundles – 3 bundles = <<10-3=7>>7 bundles of wood have been burned throughout the day.
How many bundles of wood were burned in the afternoon? ** Subtracting the wood burned in the morning from this shows that 7 bundles – 4 bundles = <<7-4=3>>3 bundles of wood were burned in the afternoon.
