14525 has 5 significant figures (s.f) significant figures help mathematicians to summarise their answer for example to give an approximation if 3 significant figures was required then the answer would be 14500 if you were asked to give 1.1235678 to 4 s.f. then the answer would 1.124 (rounding up the last digit). I hopes this help
