  2. 789 - 256 = 533 Estimation: 790 - 260 = 530

  3. 456 × 7 = 3,192 Estimation: 460 × 7 = 3,220

  4. 892 ÷ 4 = 223 Estimation: 890 ÷ 4 = 220

  5. 678 + 234 = 912 Estimation: 680 + 230 = 910

  6. 543 - 189 = 354 Estimation: 540 - 190 = 350

  7. 345 × 8 = 2,760 Estimation: 350 × 8 = 2,800

  8. 892 ÷ 6 = 149 Estimation: 890 ÷ 6 = 150

  9. 789 + 456 = 1,245 Estimation: 790 + 460 = 1,250

  10. 678 - 345 = 333 Estimation: 680 - 350 = 330
