Obviously there is an iron wire at home. The first time I use (1/2) more than 1 meter of the total length, the second time I use the remaining (1/2) more than 1 meter, and the third time I use the remaining (1/2) of the second time. /2) 1 meter more, then there is 1 meter left in the wire. How long is this wire?
明明家有一根铁丝，第一次用去总长的(1/2)多1米，第二次用去余下的(1/2)多1米，第三次用去第二次余下的(1/2)多1米，这时铁丝还剩1米．这根铁丝原来长多少米？
