Problem

Answer

89980

100000 − 10000 − 20

Step 1 — Subtract

100000 − 10000 − 20

  100000
−  10000
────────
   90000

Subtract column by column (with borrowing):

Ones: 0 − 0 = 0

Tens: 0 − 0 = 0

Hundreds: 0 − 0 = 0

Thousands: 0 − 0 = 0

Ten-thousands: 0 < 1 → borrow → 10 − 1 = 9

10⁵: 1 − 1 (borrow) − 0 = 0

Step 2 — Subtract

  90000
−    20
───────
  89980

Subtract column by column (with borrowing):

Ones: 0 − 0 = 0

Tens: 0 < 2 → borrow → 10 − 2 = 8

Hundreds: -1 < 0 → borrow → 9 − 0 = 9

Thousands: -1 < 0 → borrow → 9 − 0 = 9

Ten-thousands: 9 − 1 (borrow) − 0 = 8

= 89980
