Row Subtraction With Borrow

Subtraction can be performed by drawing sticks equal to the first digit in the question and then cross sticks equal to second digit the remaining stick gives the desired result.

For example let us solve the question

In the figure below there is a bundle of 10 sticks representing digit 1 at the tens place in the first number 12 and two sticks representing 2 at units place in the number 12.

No we have to cross 7 sticks for the second number 7.

As there are only two sticks which are less than 7 we will open the bundle to make it as 10 sticks.

Now we have 12 sticks and we will cross 7 sticks

Counting the remaining sticks we get 5 sticks.

Hence the answer is 5
