a. Use the common method to calculate
b. On graph paper, draw an array for
c. Write equations that use the distributive property and that correspond to the steps in the common method in part (a).
d. Use the common method to calculate
e. On graph paper, draw an array for 37 x 24 (or draw a rectangle to represent such an array). Subdivide the array in a natural way so that the parts of the array correspond to the steps of the common method in part (d). Compare with part (b).
f. Write equations that use the distributive property and that correspond to the steps in the common method in part (d). Are these the same equations as in part (c)?
g. Other than the distributive property, which you used in parts (c) and (f), which property of arithmetic is relevant to this problem? Explain and discuss.
