Addition With Regrouping

  • Add 28 and 35.

Steps

  • Add the Ones.
    8 Ones + 5 Ones = 13 Ones.
    13 Ones = 1 ten 3 Ones.
till(100)32.png
till(100)33.png

10 Ones = 1 ten
6 Tens and 3 Ones = 63.

Write 3 in the Ones column and take 1 ten to the Tens column.

  • Add the Tens.
    1 ten + 2 Tens + 3 Tens = 6 Tens.
    Write 6 Tens in the Tens column.
till(100)34.png

Write 3 in the Ones column and take 1 ten to the Tens column.

  • Add 58 and 26.

Subtraction (Count Backwards)

  • Subtract 6 from 50.
till(100)37.png

Start from 50. Count 6 spaces backwards. You will reach 44.So,

till(100)38.png
  • Subtract 9 from 32
till(100)39.png
So, 32 - 9 = 23.
  • Subtract 5 from 29
till(100)40.png
So, 29 - 5 = 24.

Subtracting Tens

  • Subtract 40 from 50.
    If we subtract Ones, zero subtracts zero equals to zero.
    So, we subtract the Tens only. Cross out the Tens and show it.
till(100)41.png
So, 50 - 40 = 10.
  • Subtract 60 from 90.
till(100)42.png
So, 90 - 60 = 30.

Subtraction With Regrouping

  • Subtract 28 from 42.

Steps

  • Subtract the Ones.
    2 Ones < 8Ones
    There is not enough Ones. So, we regroup:
    4 Tens and 2 Ones = 3 Tens and 12 Ones.
    12 Ones - 8 Ones = 4 Ones.
till(100)43.png
  • Subtract the Tens
till(100)44.png
  • Subtract 47 from 81.

Checking Subtraction

  • For checking subtraction, we add the number which is subtracted to the difference.
  • Subtract 36 from 52 and check the difference.
till(100)46.png

So, after checking, we can see that the sum of difference and the number which is subtracted is equal to the number which subtracts.
So, our answer is correct.

  • Subtract 56 from 89 and check the difference.
