6.2 Subtracting Across Zeros

Sometimes when you need to regroup, there is a zero in the next place. Then you need to regroup in a different way.

Method:

  1. Subtract the ones, since you cannot take away from zero, you need to regroyo. The zero becomes 10.
  2. The zero in tens place becomes 9 (since the zero in ones place takes 1 from here)
  3. Again the zero in hundreds place becomes 9 (since the zero in tens place takes 1 from here)
  4. The number in thousands place becomes less by 1(since the zero in hundreds place takes 1 from here)

Example:

  1. In ones place, 0 becomes 10.
  2. In tens place and hundreds place, 0 becomes 9.
  3. In thousands place, 4 becomes 3.
