Lernen 7 ~ Zählen von 13 bis 100

Once you have memorized the numbers from 1 to 12 (see Lernen 3), counting higher in German becomes very much like counting in English. From 13 to 19, add -zehn (10; "-teen" in English) after the cardinal number root:

13 – dreizehn (irregular in English: 'thirteen')
14 – vierzehn
15 – fünfzehn
16 – sechzehn (note that the 's' in sechs is dropped)
17 – siebzehn (note that the 'en' in sieben is dropped)
18 – achtzehn
19 – neunzehn

Above 19 the counting system is constant: add -zig ("-ty" in English) to the cardinal root. Thus, we get:

20 – zwanzig
21 – einundzwanzig (note: 'one-and-twenty')
22 – zweiundzwanzig (note: 'two-and-twenty')

And the same for 30, 40, 50....etc.

30 – dreiÃig (this is an exception to the -zig Rule)
40 – vierzig
50 – fünfzig
60 – sechzig
70 – siebzig
80 – achtzig
90 – neunzig
100 – hundert

So, combining these, we get:

34  – vierunddreiÃig (note: 'four-and-thirty')
143 – hundertdreiundvierzig (note: 'hundred-three-and-forty')
170 – hundertsiebzig
199 – hundertneunundneunzig

It would be excellent practice towards learning these numbers by counting (in German, of course) from 1 to 199—or counting along any continuous sequence that comes to mind. For example, start with your age and count to 50 (count down if appropriate).

Grammatik 7-1 ~ Math Calculations

The following table presents the symbols used for basic mathematics.

We can use these symbols to ask and answer simple problems in mathematics. Some of the examples that follow include first a question (Frage) and then the answer (Antwort):

 Wieviel ist sechs und sieben?            How much is 6 and 7?   
    Sechs und sieben ist dreizehn            6 and 7 is 13
 Wieviel ist fünfzig plus achtzehn?       How much is 50 + 18?
    Fünfzig plus achtzehn ist gleich achtundsechzig  50 + 18 = 68
 Wieviel ist siebzig minus zehn?          How much is 70 - 10?
    Siebzig minus zehn ist gleich sechzig     70 - 10 = 60
 Wieviel ist neun durch drei?             How much is 9 divided by 3?
    Neun durch drei ist gleich drei          9 ÷ 3 = 3
 Funf ist gröÃer als zwei                 5 > 2
 Acht ist kleiner als siebzehn            8 < 17
