ordinal math question

Question

my child's homework asked them to write out the following ordinals: 10, 24, 20, 37, 15 etc.

My question is, after each number there was a degree and period symbol...what is the meaning of these symbols?

I know the ordinal translations were: tenth, twentyfourth, etc.

1.º = primero
1.ª = primera
1.º = segundo
2.ª = segunda
3.º = tercero (3.ª, etc.)
...
10.º = décimo
11.º = décimo primero / undécimo
12.º = décimo segundo / duodécimo
20.º = vigésimo
30.º = trigésimo
40.º = cuadragésimo
50.º = quincuagésimo
60.º = sexagésimo

We had a recent discussion saying that was no longer true (in Spain I think it was, as least). You might want to search for it using 10^9 and 10^12.

No longer true in Spain'''?
I've just checked with a younger cousin of mine, who is still in primary school, and they still use 12 zeroes for the billion. The long system is also used in most parts of Europe (except the UK).

Thank you for the quick feedback. The homework is from a spanish emersion program my child is in...I can translate the problem statement, and I'm comfortable with the "math translation"...I just don't get the period and degree symbols - I'm wondering if this is something specific to spanish notation '?

Here is the exact problem statement: "Ejercicios de repase. Escribe los nombres de los siguientes numeros ordinales:

10.°

13.°

24.°

etc.

When counting in Spanish the ordinals end with the letter "o" e.g. primero, segundo, tecero, etc.
(They can also be used as adjectives so, when modifying a noun they need to agree in gender and number but if you're just counting [in the abstract] they use "o"). What you're referring to as the "degree symbol" is a superscript "o" similar to the "st","nd","rd", etc. that can be written in English after a digit to represent "first",'second",'third".

If you want to say 1'10^9 mathematically in spanish you say mil millones, but sometimes people do bad translations and then we get use to it.
