The quiz that is presented here gives an experience to the child about how to subtract two numbers when they are unequal in length. The number which has number of digits has to be placed first and then the number which has the lesser number of digits has to follow it. After rearranging it, the usual subtraction routine has to be performed wherein the techniques of regrouping and borrowing come into the scene. The questions in the quiz give a good practice to the kids in creating awareness on the logic behind subtraction.

How to subtract two digit number from three digit numbers?

Subtraction is a mathematical operation that is used to find the difference between two numbers. When subtracting two-digit numbers from three-digit numbers, it’s important to understand the place value of each digit and to follow the standard subtraction algorithm.

The place value of a digit tells us the value of that digit in a number. For example, in the number 356, the 3 is in the hundreds place, the 5 is in the tens place, and the 6 is in the ones place. Knowing the place value of each digit is important when subtracting because it helps us to understand which digits we are working with and how to line up the numbers correctly for subtraction.

To subtract two-digit numbers from three-digit numbers, we line up the numbers so that the digits are in their correct place value columns. For example, when subtracting 57 from 356, we would line up the numbers like this:

  356
-  57
-----

Next, we start subtracting from the rightmost column (the ones column) and work our way to the left. In the ones column, 6 – 7 = -1. This means that we need to borrow 1 from the tens column. So we change the 5 to 4 and add 1 to the 6, making it 7. Now the subtraction is 7 – 7 = 0.

We then move on to the tens column, where we have 4 – 5 = -1. Again, this means that we need to borrow 1 from the hundreds column. So we change the 3 to 2 and add 1 to the 4, making it 5. Now the subtraction is 5 – 5 = 0.

Finally, we move on to the hundreds column, where we have 2 – 3 = -1. This means that the final answer is -1, with the negative sign indicating that the result of the subtraction is less than zero.

It’s important for kids to understand that when subtracting two-digit numbers from three-digit numbers, it’s sometimes necessary to borrow from the next column. This is a important step to remember when solving these types of subtraction problems.

Another way to help kids understand the subtraction is through word problems. For example, you can give them a problem like: “If a toy store has 356 toys and they sell 57 of them, how many toys do they have left?” This will help them understand how subtraction is used in real-life situations.

It’s also important to practice with more challenging examples, such as subtracting three-digit numbers from four-digit numbers and using regrouping/borrowing again. It’s also important to make sure that children understand that subtraction is not commutative operation and that the order of numbers does matter.

In the end, subtraction is an important mathematical operation that is used in many different areas of life. It’s a skill that kids will use throughout their lives, and the more practice they have, the better they will become at it.
