Steps to Solve
- Solving the first part: Basic Addition To solve basic addition problems, add the integers as follows:
- 1: $14 + 8 = 22$
- 2: $25 + 48 = 73$
- 3: $31 + 12 = 43$
- 4: $-3 + (-2) = -5$
- 5: $7 + 9 = 16$
- 6: $14 + 6 = 20$
- 7: $30 + (-22) = 8$
- 8: $0 + 12 = 12$
- 9: $0 + (-21) = -21$
- 10: $18 + (-6) = 12$
- Solving the second part: Algebraic Expressions In part B, simplify the expressions:
- 1: $[1 + 1] = 2$
- 2: $[2 + (-3)] = -1$
- 3: $[3 + (-1) + (-2)] = 0$
- 4: $[1 + (-4)] = -3$
- Interpreting Contextual Problems: Read and solve word problems by translating the words into mathematical operations:
- 1: Jake earned $37 last week, making a total of $25 in savings. His current total savings will be $37 + 25 = 62$.
- 2: Michelle’s total score from the tests is computed by adding all her scores. Add them: $4 + (-5) + 3 + (-2) = 0$.
The completed answers for the problems are:
