Subtracting 2 and 3 Digit Numbers without Regrouping
The boys' basketball banquet is coming up and you've been selected as the treasurer. You've collected a total of $97 from all the players. The food will cost $74 and you will still need $20 in order to buy certificates. Do you have enough money to buy the food and the certificates? How can you figure out if this is possible?
Subtracting means taking away one number from another number. When you are performing subtraction, sometimes you will have to regroup, or carry over, and sometimes you will not. Regrouping is only necessary in subtraction when the top number is smaller than the bottom number being subtracted. For example: if I had 4 marbles, I could not subtract or take away 6 marbles because the number 4 is less than the number 6. In this lesson, we will only be subtracting numbers that do not need to be regrouped. Subtracting without regrouping can be done mentally, or in your head, because the numbers can be easily deducted since the top number is always larger than the bottom number.
How to Subtract 2 Digit Numbers
In order to figure out if you have enough money to buy the food and the certificates, we need to set up our problem. Our number sentence would look like the example below:
9 7
- 7 4
Whenever we subtract, we always start with the numbers in our ones place, then tens, next hundreds, and so on. If we subtract the numbers in our ones place, our number sentence will be 7 - 4 = 3. We would then move to our tens place. That number sentence would be 9 - 7 = 2. Our difference, or answer, would be 23.
9 7
- 7 4
= 2 3
Now that we've found our difference, we can answer the question. Do you have enough money to buy the food and the certificates? The answer is yes because $23 is more than $20. Being able to subtract 2 digit numbers without regrouping makes it easy for you to figure out when you have enough or when you need more.
