Phone Numbers, Arithmetic and Reading Figures | Finnish Grammar

There are two everyday situations where you read numbers aloud as raw figures rather than as counted quantities: reciting a phone number and doing arithmetic. Both have their own small conventions. A phone number is read digit by digit, not as one gigantic number, and a sum uses a handful of operator words — plus, miinus, kertaa, jaettuna — strung together with on ("is/equals"). This page gives you the digits, the phone-number habit, and the spoken maths.

The digits, including nolla

Reading figures starts with the ten single digits. The one you have not met while counting objects is nolla ("zero") — you never say "zero apples," so it only shows up in figures, codes, scores and temperatures.

Figure	Finnish	Figure	Finnish
0	nolla	6	kuusi
1	yksi	7	seitsemän
2	kaksi	8	kahdeksan
3	kolme	9	yhdeksän
4	neljä	10	kymmenen
5	viisi

Nolla also does the work of English "nil / love / zero" in scores and readings:

Suomi voitti ottelun kaksi–nolla.

Finland won the match two–nil.

Ulkona on tänään nolla astetta.

It's zero degrees outside today.

Reading a phone number: digit by digit

A Finnish phone number is spoken as a sequence of single digits, not decoded into thousands and hundreds. So the code 012 is nolla–yksi–kaksi, never "twelve." Speakers usually chunk the number into small groups — the operator prefix, then two- or three-digit clusters — pausing between clusters, but each cluster is still read one figure at a time.

Numeroni on nolla–neljä–nolla, viisi–kaksi–yksi, kolme–kuusi–seitsemän–kahdeksan.

My number is oh-four-oh, five-two-one, three-six-seven-eight.

Ovikoodi on nolla–yksi–kaksi–kolme.

The door code is zero-one-two-three.

💡

The instinct to read 012 as "twelve" (kaksitoista) is the number-one figure-reading mistake for English speakers. Codes, PINs and phone numbers are strings of separate digits: nolla–yksi–kaksi. Save the big compound numbers (kaksitoista, tuhat) for actual quantities.

Double digits are sometimes read as a two-digit number for speed (040 as nolla, neljäkymmentä — "oh, forty"), but the safe, always-understood method is one figure at a time. Start there.

Spoken arithmetic: the operator words

A calculation is built from an operator word between the numbers and the verb on ("is") for the result. The four operators:

Operator	Finnish	Symbol
plus	plus	+
minus	miinus	−
times	kertaa	×
divided by	jaettuna (+ adessive)	÷

Addition and subtraction are straightforward — the loanwords plus and miinus sit between the numbers, and on gives the result:

Kaksi plus kaksi on neljä.

Two plus two is four.

Seitsemän miinus kolme on neljä.

Seven minus three is four.

Multiplication uses kertaa — literally "times," the partitive of kerta ("a time, an instance"):

Kolme kertaa neljä on kaksitoista.

Three times four is twelve.

Division uses jaettuna ("divided"), and the number you divide by takes the adessive ending -lla / -llä ("by two" = kahdella):

Kymmenen jaettuna kahdella on viisi.

Ten divided by two is five.

💡

For the result you can say plain on ("is") or, more explicitly, on yhtä kuin — literally "is as much as," the spoken form of the equals sign =. So kaksi plus kaksi on neljä or kaksi plus kaksi on yhtä kuin neljä. In casual talk you'll also hear tekee ("makes"): kaksi plus kaksi tekee neljä(informal).

The four operations also have noun names, useful in a classroom: yhteenlasku (addition), vähennyslasku (subtraction), kertolasku (multiplication), jakolasku (division), and the verb laskea ("to calculate"). You may also meet ynnä as an old word for "plus" — now (archaic) in arithmetic, surviving mainly in the fixed phrase ynnä muut ("and others, et al.").

Decimals: the pilkku reader

Finnish separates the whole part from the fraction with a comma (pilkku), not a point — 3,5 — and reads the comma aloud as pilkku:

Kolme pilkku viisi on enemmän kuin kolme.

Three point five is more than three.

Sain kokeesta arvosanan kahdeksan pilkku viisi.

I got a grade of eight point five on the exam.

So 2,75 is kaksi pilkku seitsemänkymmentäviisi ("two comma seventy-five"). In everyday talk halves are often just spoken out — kaksi ja puoli ("two and a half") for 2,5. The full treatment of decimals and fractions, including how the fractional digits are read, is on the fractions and decimals page; the writing conventions for figures are on writing numbers.

💡

Never import English "point" for the decimal. Finnish uses pilkku ("comma"), matching the comma it writes: 3,5 is read kolme pilkku viisi. A "point" (piste) in Finnish is the full stop that groups thousands in writing (1.000), the exact reverse of English punctuation.

Common Mistakes

❌ Ovikoodi on kaksitoista kolme.

Incorrect — codes and phone numbers are read digit by digit: yksi–kaksi–kolme, not 'twelve three'.

✅ Ovikoodi on yksi–kaksi–kolme.

The door code is one-two-three.

❌ Kolme piste viisi.

Incorrect — the decimal separator is read pilkku ('comma'), not piste ('point'): kolme pilkku viisi.

✅ Kolme pilkku viisi.

Three point five (3,5).

❌ Kymmenen jaettuna kaksi on viisi.

Incorrect — the divisor takes the adessive -lla: jaettuna kahdella.

✅ Kymmenen jaettuna kahdella on viisi.

Ten divided by two is five.

❌ Kolme kertaa neljä ovat kaksitoista.

Incorrect — the result verb is the singular on ('is'), not the plural ovat: on kaksitoista.

✅ Kolme kertaa neljä on kaksitoista.

Three times four is twelve.

Key Takeaways

The digits are nolla, yksi, kaksi, kolme, neljä, viisi, kuusi, seitsemän, kahdeksan, yhdeksän — nolla is the "figures-only" zero.
Read phone numbers and codes digit by digit (nolla–yksi–kaksi), chunked into small groups — not as one big number.
Arithmetic operators: plus, miinus, kertaa ("times"), jaettuna + adessive ("divided by"); the result takes on ("is") or on yhtä kuin ("equals").
Decimals use a comma read as pilkku — 3,5 = kolme pilkku viisi — never English "point."
