Thank you for explaining it.

S 45° E means 90 + 45 = 135 135/10 = 13.5 so its nearest value 13 and 360-45=315 315/10= 31.5 near value 31.

How it is 13 and 31? Explain it.

Divide its magnetic heading by 10, round it to the nearest whole number and you will usually get the runway number.

For example, if the magnetic heading is 345° then 345/10 = 34, 5.

So the runway number will be 35 which will be a runway used for landings (and takeoffs) to the north.
