Next in Series: Addition of Threes, Sevens, and Nines

Do you think you know addition? Let's try doing three addition problems at a time. Instead of asking you to add one number, we're going to ask you to use three numbers. This activity has you adding by 3, 7, and 9. Since all of these numbers are odd, you may see connections between the sums. All of the questions use random starting values.

For example, you will need to answer the following questions:
3 + 3, 3 + 7, and 3 + 9

Good luck and have fun.

Directions

This quiz tests asks you to complete several actions on one number. You will need to finish three parts for each question. After you click your answer, you will see the correct sum and the next question. When you have finished the three, you will notice patterns and the following questions should become easier.

You get a happy face for every correct answer and a sad face for every wrong answer. The quiz is over after three (3) questions. Take the quiz again and again because all of the questions are random. You should get a new quiz every time. It's good practice to learn these basic arithmetic comparisons.
