This is just to make it easier to tell a 7 with a short top bar from a 1.
In French, the number 1 has an exaggerated upstroke (line from left) rather than a single vertical line, and the crossbar is often required to tell a 1 and 7 apart.
Similarly, a line may be placed diagonally thru a zero (0) to differentiate it from a capital O : ∅.
But in Danish, the exact opposite is done, where a line indicates a capital o (Ø).
Where to put 0.311 in a number line
It IS on a Number Line. Set of Integers.
you put a dash where the correct number is.
Any number that you can put on the number line is real.

No. Look 7 the top and bottom are uneven lengths and no matter what angle you put the line of symmetry at, there will still be no proper symmetry line
Put 8.98 a little to the left of the number 9 on the number line.
Where to put 0.311 in a number line
The Roman number for 7000 could be written two ways. One could put seven M's in a row but that would be awkward. (M is the Roman numeral for 1,000) The common way of writing 7000 would be to use the numeral VII (seven) and put a line over it. This line means that the number is multiplied by 1,000.

yes you can so if you put two lines meeting at a 90' angle then put as many marks on the lines but make sure you put the same amount of marks on each of the line then number the mark on one line then the number number you started with goes at the end of the line you havent numbered the join the numbers up
Put it on the memo line
You model your equation on a number line to using a bar model.
