Practice 2

To practice your arithmetic skills, take the following drill without a calculator. Then, look at the trivia question at the end of the lesson. Match your answer and its corresponding letter to the number answers that complete the trivia answer. (If you need to, you can rewrite these questions in a different form—stacking addition problems or using long division, for example.)

1. 17 + –4 = W
2. 174 + 58 = L
3. 1,023 + 75 = E
4. 99 – 16 = C
5. –3 – – 5 =I
6. –59 – 18 = L
7. 9 × 7 = A
8. –15 × –3 = S
9. 100 × –3 = O
10. 125 ÷ 25 = R
11. –81 ÷ –9 = R
12. –258 ÷ 3 = L
