Übung 29 Wieviel ist das? Eerapa jumlahnya? Beispiel: fünf + acht =dots fünf plus acht ist dreizehn. vierzig + sieben + zwanzig =dots sieben + achtig + drei =dots . neunzig - vierzig =dots . achtzehn - achtzehn =dots . acht xx drei - neunzehn =dots . sechsunddreißig : drei xx elf = z wanzig xx fünf : vier =dots . siebzehn - elf + achtzig =dots . einundachtzig : neun xx drei =dots . vierzig - zwölf xx drei =dots .

1. 67 2. 90 3. 50 4. 0 5. 5 6. 132 7. 25 8. 86 9. 27 10. 4

To solve these arithmetic problems, we perform the following calculations: 1. Add 40, 7, and 20 to get the sum. 2. Add 7, 80, and 3 to get the sum. 3. Subtract 40 from 90 to get the difference. 4. Subtract 18 from 18 to get the difference. 5. Multiply 8 by 3, then subtract 19 from the product. 6. Divide 36 by 3, then multiply the quotient by 11. 7. Multiply 20 by 5, then divide the product by 4. 8. Subtract 11 from 17, then add 80 to the difference. 9. Divide 81 by 9, then multiply the quotient by 3. 10. Subtract 12 from 40, then multiply the difference by 3.
