It’s Wednesday – here are some problems to solve

Try solving this with the 1-step standard algorithm.  We are working to solve problems as efficiently as we can, while at the same time being accurate.

Have fun and learn some fun facts about the countries we are researching along the way.


Tera discovered there are 126,372,364 people living in Japan.  Samantha found out there were 68,377,173 people living in Thailand.  How many people did they find when they added the populations together?

Katie learned that the Sydney Opera House was built in three sections.  It was started in 1959 and was finished in 1973.  How many years did it take for the Sydney Opera House to be built?  How many years ago was it finished?

Lucy found out the the Great Wall of China is 13,171 miles long.  The United States is 2,802 miles across from Florida to Washington state.  How much longer is the Great Wall of China than the United States?

  1. Question 1. The total population is 194, 749, 537 people.

    Question 2. It took 14 years to build. 1973-1959=14.
    And it was built 44 years ago. 2017-1973=44.

    Question 3. The Great Wall is 10, 369 miles longer than the length of the USA east to west. 13,171- 2,802= 10,369.

    • Wow Max! You did all of them and so efficiently. I as so surprised to learn that the Great Wall was that much longer than our whole country is across. That is really big! Thanks for your effort and time. Mrs. Eaves

    • Hi Liam, Thanks for taking the time to work with these super large amounts. I agree with most of your answer – check the hundreds, tens and ones. I get an answer that is a bit different from what you typed.
      Thanks for taking the time and making the effort to work with these amounts.
      Mrs. Eaves
