  1. How do you rewrite equations so that the answer, or variable remains the same?

  2. Which equation is the same as….25 – (8 + 6) • (25 + 8) – 6 • 25 – (6 + 8) • (25 – 8) + 6 • (8 + 6) – 25

  3. Which equation is the same as….90 – (15 + 6) • 90 – (6 + 15) • (15 + 6) - 90 • 90 + 15 - 6 • (90 – 15) + 6

  4. Which equation is the same as….(8 + 12) - 10 • 10 – (8 + 12) • 8 + (10 - 12) • (8 + 10) - 12 • (12 + 8) – 10

  5. Which equation is the same as….3(4 + 5) • 4(3 + 5) • (3•4) + (3•5) • (4 + 5) / 3 • 5(3 + 4)

  6. Which equation is the same as….3s – 9 = 15 • 3s = 15 – 9 • -9 = 15 + 3s • 3s = 15 + 9 • 9 = 15 / 3s

  7. Which equation is the same as….25 = 3b + 10 • 25 – 10 = 3b • 25 / 10 = 3b • 3b = 25 + 10 • 25 + 3b = 10

  8. Which equation is the same as….j(5 + 4) • (j + 4)5 • 4(j + 5) • j • 5 • 4 • (5j) + (4j)

  9. Which equation is the same as….r(8 + 7) • (r + 8)7 • 8(r + 7) • 8r + 7r • r + 8 + 7

  10. Which equation is the same as….4(q + b) • 4q + 4b • 4 – (q + b) • 4 + q + b • (4q) + b

  11. Which expression is equivalent to: 6(8y + 12) a. (6 • 8)y + 12 b. (6 • 8 • 12)y c. (6 • 8) + (6 • 12)y d. (6 • 8)y + (6 • 12)

  12. Which expression is equivalent to: 2(a + 6) + 3a a. 11a b. 36a c. 5a + 6 d. 5a + 12
