#	Year	Section	Page	Question	Given	Correct	Note
1	Year 9	Exercise 1:01	Page 2	3.p.	${\frac {57}{72}}$	${\frac {19}{24}}$	don't cha know your 19 times tables?
2	Year 9	Exercise 1:01	Page 2	4.o.	$0.475$	$0.0475$	off by an order of magnitude
3	Year 9	Exercise 1:02	Page 4	3.d.	$6.375$	$6.35$	${\frac {6.4-6.3}{2}}+6.3=6.35$
4	Year 9	Exercise 1:02	Page 5	11.	$54{\text{ BC}}$	$54{\text{ BCE}}$	both are technically correct but better to be consistent
4	Year 9	Exercise 1:02	Page 6	23.a.	${\frac {ad+bc}{bd}}$		is not rational if $bd=0$
4	Year 9	Exercise 1:02	Page 6	23.b.	${\frac {ad-bc}{bd}}$		is not rational if $bd=0$
4	Year 9	Exercise 1:02	Page 6	23.c.	${\frac {ac}{bd}}$		is not rational if $bd=0$
4	Year 9	Exercise 1:02	Page 6	23.d.	${\frac {ad}{bc}}$		is not rational if $bc=0$
