<human>:  A 10 m long and 8 m wide rectangular floor is to be covered with a square carpet with 4 m sides. How many square meters of the floor are uncovered?
<bot>: How many square meters are in the floor? ** The area of the floor is 10 m x 8 m = <<10*8=80>>80 square meters.
How many square meters are in the carpet? ** The area of the carpet is 4 m x 4 m = <<4*4=16>>16 square meters.
How many square meters of the floor are uncovered? ** Therefore, the area of the floor not covered by the carpet is 80 square meters - 16 square meters = <<80-16=64>>64 square meters,
