“2{“version”:”1.1″,”math”:”2″} is a multiple of 18{“version”:”1.1″,”math”:”18″}.”

True/False: “All prime numbers are odd.” If TRUE, click on true. If FALSE, click on false and then on your paper name at least one prime number that is even. 

On your paper, Draw and use the model below or use the model given for problem #21 on the drawing sheet for the Final exam that was given in the news feed on D2L to clearly explain where to put the decimal point given that 28×36=1008{“version”:”1.1″,”math”:”28×36=1008″}. Be sure to count the squares accurately. Click “Complete” when you have completed your work on this problem or are ready to move on. 

On your paper, Compute the product of 17×27{“version”:”1.1″,”math”:”17×27″} using the partial products algorithm and the standard algorithm (also known as the common method). • Label the products in the partial products algorithm.• Label the products in the standard algorithm.• Show how the products in the standard are related to the products in the partial products algorithm.                          Partial Products                              Standard (Common) (b) Show how to calculate 17×27{“version”:”1.1″,”math”:”17×27″} step-by-step by writing equations that use the distributive property of multiplication over addition and expanded forms based on the partial products algorithm. Hint: Be careful not to skip any steps.  (c) Make a sketch of the dots below or use the array of dots given for problem #17 on the drawing sheet for the Final exam that was given in the news feed on D2L.   (An area model will also suffice.) Subdivide the dots in a natural way so that the parts correspond with the standard algorithm (also known as the common method) used to calculate the product of 17×27{“version”:”1.1″,”math”:”17×27″}. Accurately and clearly label all parts of the diagram so that the subdivision corresponds with the steps. The diagram below is 40{“version”:”1.1″,”math”:”40″}-dots-by-40{“version”:”1.1″,”math”:”40″}-dots. The line marking on the diagram are only there to help count the dots. Be sure to count the dots accurately. Click “Complete” when you have completed your work on this problem or are ready to move on. 

“7{“version”:”1.1″,”math”:”7″} is a factor of 107{“version”:”1.1″,”math”:”107″}.”
