> · Open end points to the larger number.
True · Equals means same value.
6 · A cuboid has 6 faces.
8 cm · A measurement answer needs its unit, like cm, so everyone knows what was measured.
The unit, like cm · A number alone doesn't say what was measured. Add a unit such as cm or m.
3 is less than 5 · 3 is smaller than 5.
True · Edges are face joins.
45 cm is greater than 32 cm · 45 is more than 32.
He should have used <, because 3 is less than 9 · 3 is smaller than 9, so the correct symbol is <, not >.
8 does not equal 11, so the = sign is used wrongly · Each = sign must join two equal amounts. Since 8 and 11 are not the same, this is not a correct use of =.
