Farmer Claus has $210$ sheep, $100$ cows and $55$ chickens on his farm, in addition to his dogs Molly and Bello. How many animals does he have in total?

Für diese Aufgabe benötigst Du folgendes Grundwissen: Written method of addition
First calculate the number of sheep and cows:
$\displaystyle \def\arraystretch{1.25} \begin{array}{cccc} &2&1&0\\ +&1 & 0 & 0 \\ \hline &3&1&0\end{array}$
Add the $55$ chickens:
$\displaystyle \def\arraystretch{1.25} \begin{array}{cccc} &3&1&0\\ +&&5&5 \\ \hline &3&6&5\end{array}$
And don't forget the two dogs:
$\displaystyle 365 + 2= 367$
Answer: Claus has $367$ animals on his farm

Add in writing! Enter your result in the text field to check it.
1. $\def\arraystretch{1.25} \begin{array}{cccc} &9&9&9\\+&&1&3&\\ \hline\end{array}$
  
  Für diese Aufgabe benötigst Du folgendes Grundwissen: Written method of addition
  1. Step: Add the ones.
  $3+9=\textcolor{orange}{12}$
  This is more than 9. So you need to "drag the 10" one position to the left in order to "memorize" it.
  $\def\arraystretch{1.25} \begin{array}{cccc} &9&9&9\\+&&_{\textcolor{orange}{1}}1&3&\\ \hline &&&\textcolor{orange}{2}\end{array}$
  2. Step: Add the tens.
  Don't forget to add the "remembered" tens.
  $9+1+1=\textcolor{orange}{11}$
  This is more than 9. So drag the 10 one position forward to the 100s and thus "memorize" it.
  $\def\arraystretch{1.25} \begin{array}{cccc} &9&9&9\\+&_{\textcolor{orange}{1}}&_{1}1&3&\\ \hline &&\textcolor{orange}{1}&2\end{array}$
  3. Step: Add the hundreds.
  Don't forget to add the "remembered" hundredths.
  $9+1=\textcolor{orange}{10}$
  Drag the 10 one step forward to the 1000s $\def\arraystretch{1.25} \begin{array}{ccccc} &&9&9&9\\+&&_{1}&_{1}1&3&\\ \hline &\textcolor{orange}{1}&\textcolor{orange}{0}&1&2\end{array}$
  The final result is $1012$ .

Add the numbers in columns.
347, 412, 19, 165

$\def\arraystretch{1.25} \begin{array}{rrrr} & 3& 4&7&\\ +& 4& 1&2&\\ +& & 1&9&\\ +&_1 1&_2 6&5&\\ \hline\\ &9&4&3& \end{array}$

6
Find the missing number.
153 + 84 + 27 + ____ = 400

153 + 84 + 27 = 264 hence the missing number is 136 as 264 + 136 = 400.

A word problem
The curator of a small museum wants to buy a painting by a well-known local artist. It is to be sold for 5,610 €. Unfortunately, there are no funds for this acquisition. Citizens have been asked to make donations so that the purchase can go ahead.
Donations have indeed been coming in: 3,487 € (local shops), 250 € (Mr & Ms Miller), 105 € (Ms Cooper), 280 € (Mr Carter), 1000 € (A & B Bank), 14.51 € (Chris), 634 € (staff Electricity Board).

3487 + 250 + 105 +280 + 1,000 + 14.51 + 634 = 5,770.51 The painting can be bought.
