Subtraction of two digit numbers basic Math test
After doing the quiz on subtracting a single digit number from a two digit number, now it makes the right time to notch up a step higher as this quiz involves subtracting a two digit number from another two digit numbers and this time the numbers are also big. During the process of solving these questions, the child gets to see that he needs to know about borrowing values from the adjacent numbers and thus, this helps to make the child master on the concepts of subtraction. It is a good exercise since the quiz is bound with a timer running down.
How to subtract two digit numbers?
Here is a guide on how to subtract two-digit numbers for kids:
- First, line up the two numbers on top of each other, making sure that the units (ones) digits are lined up and the tens (tens) digits are lined up.
- Next, start with the units (ones) digits and subtract the bottom number from the top number. If the bottom number is larger, you may need to borrow from the tens (tens) digits. For example, if the top number is 17 and the bottom number is 12, you would subtract 2 from 7 to get 5.
- Next, move on to the tens (tens) digits and subtract the bottom number from the top number. If you had to borrow from the tens (tens) digits in step 2, remember to add 1 to the top number before subtracting.
- Once you have subtracted the tens (tens) digits, you can write your final answer. Make sure to put the units (ones) digit in the units (ones) place and the tens (tens) digit in the tens (tens) place.
For example, let’s say you want to subtract 44 from 63. First, line up the numbers like this:
63 -44
Then, start with the units (ones) digits:
63 -44 =19
Next, move on to the tens (tens) digits:
63
-44
19
And finally, write your final answer:
63
-44
19
The final answer is 19.
