### Basic Numbers in Norwegian

Let’s start with the basics. Numbers are the foundation of any mathematical discourse and are crucial for many everyday interactions such as shopping, telling time, or giving an address.

The numbers one to ten in Norwegian are as follows: en (one), to (two), tre (three), fire (four), fem (five), seks (six), sju (seven), åtte (eight), ni (nine), and ti (ten).

To practice, consider how you might use these in everyday sentences:

– Jeg har to søstre. (I have two sisters.)
– Kan jeg få fire epler? (Can I have four apples?)

### Numbers Beyond Ten

Once you are comfortable with the first ten numbers, you can easily learn higher numbers which build on these basics.

Numbers like eleven (elleve) and twelve (tolv) might need some memorization, but from thirteen to nineteen, the numbers are formed by simply adding the suffix –ten to the numbers four through nine. For example, fjorten (fourteen), femten (fifteen), seksten (sixteen).

The tens are also systematic:
– tyve (twenty),
– tretti (thirty),
– forti (forty),
– femti (fifty),
– seksti (sixty),
– søtti (seventy),
– åtti (eighty),
– ni-ti (ninety).

Combining these can help form other numbers:
– En og tyve (twenty-one),
– To og tretti (thirty-two).

Here’s how you might use them:
– Det er tretti grader ute. (It is thirty degrees outside.)
– Hun er tyve år gammel. (She is twenty years old.)

### Higher Numbers and Counting

For numbers in the hundreds and thousands, you would use hundre (hundred) and tusen (thousand). Larger numbers continue building in a similar pattern:
– En hundre (one hundred),
– To hundre (two hundred),
– Et tusen (one thousand),
– To tusen (two thousand).

Discussing larger quantities:
– Jeg har spart fire tusen kroner. (I have saved four thousand kroner.)
– Det var over tre hundre mennesker der. (There were over three hundred people there.)

### Basic Mathematical Operations

Now let’s delve into basic mathematical operations, which are crucial for more technical discussions or even simple tasks like splitting a bill.

The basic operations include:
– Addisjon (+) – pluss
– Subtraksjon (-) – minus
– Multiplikasjon (*) – ganger
– Divisjon (/) – dividert med

Examples in use:
– Fem pluss to er sju. (Five plus two is seven.)
– Ti minus fire er seks. (Ten minus four is six.)
– Tre ganger fire er tolv. (Three times four is twelve.)
– Tjue dividert med fem er fire. (Twenty divided by five is four.)

### Practical Applications and Phrases

When learning a new language, applying your knowledge in practical contexts is essential. Here are a few phrases that incorporate numbers and mathematical terms, useful in everyday situations:
– Kan du dele regningen i to? (Can you split the bill in two?)
– Hvor mange kilometer er det til nærmeste by? (How many kilometers is it to the nearest town?)
– Jeg trenger seks liter melk. (I need six liters of milk.)

### Conclusion

Mastering numbers and basic mathematical terms in Norwegian not only enhances your vocabulary but also boosts your confidence in handling everyday transactions and interactions in Norway. With practice, these terms will become second nature, allowing you to engage more deeply with the language and culture.
