To round to x significant digits: count x digits from the left if the next digit is 5 or greater, add one to your last digit add zeroes to round if necessary So 1026 = 10|26 = 10 Next digit = 2, so leave it Add zeroes = 1000 1026 to 2 s.f.

1026 is 4 significant figures. So look at the last pair, and ask yourself whether 26 is nearer 0 or nearer 100. It’s nearer 0, so you knock it out, and substitute 0’s. 1,000.
