#### SUBTRACTION CALCULATOR WITH STEPS

Enter two positive numbers.

SOLUTION STEPS

The Last Step:

Thousands place:

Subtract the numbers in the thousands place.

60 = 6

Write 6 to the thousands place.

All Steps:

Ones place:

2 < 3

Borrow 1 from the tens place.

Tens place:

After borrowing from the tens place the number in the tens place reduces by 1 and and becomes 0

11 = 0

## INFORMATION

### LONG SUBTRACTION

Follow the steps below in long subtraction.

• Write the numbers so that the same places are aligned in the same column.

• Start subtracting numbers from the right-most digit and each time move one digit to the left.

• In any digit, if the number on top is greater than or equal to the number on bottom, do the subtraction and write the result to the same place.

• If the number on top is smaller than the number on bottom, move left until a non-zero number is reached on top.

• Borrow 1 from the first non-zero number and reduce it by 1.

• Add 10 to one digit right and move to that digit.

• Continue regrouping and adding 10 to the lower digit until the digit to be subtracted is reached.

• Do the subtraction and move one digit left.
