Student Number Math 211 Take Home Exam 2 Andy Callison, Travis Marshall, Karen Repko, Angela Dobbins 1. + 1 2 3 4 5 6 1 2 3 4 5 6 10 2 3 4 5 6 10 11 3 4 5 6 10 11 12 4 5 6 10 11 12 13 5 6 10 11 12 13 14 6 10 11 12 13 14 15 a. 1 4 1 3 5 seven b. 3 4 1 3 5 seven + 2 4 2 seven _-2 4 2 seven 1 0 1 0 seven 1 6 3 seven Part (a) from right to left reads: 5 + 2 = 10, 1 + 4 + 3 = 11, 1 + 4 + 2 = 10. Part (b) from right to left reads: 5 -2 = 3, and since we don’t have enough to subtract 4 from 3 in the 7’s column, we will decompose (borrow) from the next column (the 49’s column) making it 13 – 4 = 6. Finally, 3 – 2 = 1. 2. * 1 2 3

Part (b) from right to left reads: 3 goes into 12 2 times. We multiply 3 * 2 = 12 and write 12 underneath and subtract to get 0. 3 goes into 0, 0 times with no remainders. 3. (A – B) – C + A B C A C A B B A B C C B C C Since we are shown an expression using subtraction, but only given a table using addition, we will need to use the Inverse Relationship of Addition and Subtraction to simplify the expression. If A + B = A, then A – B = A. So, when substituting (A) for (A – B) the expression becomes (A) – C. Then, if C + C = A, then (A) – C = C. So we can evaluate the expression as (A – B) – C = C. 4. a n = 4( n + 1)
This shows the structures increasing in sort of a pinwheel fashion. 4 sides with the number of blocks per side equal to the structure number plus one. a n = (2 n + 4) + 2 n This shows the structures by finding the top and bottom rows of blocks first: ( 2 n + 2 ), then finding the left and right sides: ( 2 n ) a n = 4 + 4 n
