  3. 1. Rewrite using just the number 7 4·7 Gabriel Lucas - Math 70.08

  4. A: 7 + 7 + 7 + 7 Which one? B: 7 · 7 · 7 · 7 Gabriel Lucas - Math 70.08

  5. A: 7 + 7 + 7 + 7 Answer: A because 4 · 7 = 4 sevens = 28 B: 7 · 7 · 7 · 7 Gabriel Lucas - Math 70.08

  6. 2. Rewrite using just the letter d 3d Gabriel Lucas - Math 70.08

  7. A: d + d + d Which one? B: d · d · d Gabriel Lucas - Math 70.08

  8. A: d + d + d Answer: A because 3d = 3 d’s = d + d + d B: d · d · d Gabriel Lucas - Math 70.08

  9. Rule 1 a(x) = x + x + … + x + x ? Gabriel Lucas - Math 70.08

  10. Rule 1 a(x) = x + x + … + x + x a Gabriel Lucas - Math 70.08
