Matt rode his bike away from the house, he rode a total of 1000 feet.  Along the way, he passed a stop sign that was 350 feet away from his house.  He continued his ride and passed a second sign.  After passing the second sign he road an additional 275 feet.  How many feet are between the first and second signs?
Matthew rode 350 feet to the first sign, so there are 1000-350 =<<1000-350=650>>650 feet between the first sign and the end.
After passing the second sign Matthew road 275, so 650-275 = <<650-275=375>>375 feet remain.
