1. Subtracting Two to Three Digit Numbers W/out Regrouping

2. Objective: Visualize, represent and subtract 2- to 3 digit numbers with minuends up to 999 without regrouping.

3. Subtraction May mean: Taking away from a given set Comparing two sets Finding the missing addend The inverse or opposite of addition

4. How to subtract the two to three- digit numbers without regrouping?

5. Step 1: Write the minuend and subtrahend in columns.

6. 557- 431= N 557 -431

7. Step 2: Begin subtracting the ones then the tens, the hundreds and so on, up to the greatest place value.

8. a. Subtract the ones. 55 7 -43 1 6

9. b. Subtract the tens. 5 5 7 -4 3 1 2 6

10. c. Subtract the hundreds. 5 57 - 4 31 1 26

11. Check the difference by adding the difference and subtrahend. Step 3:

12. 557 Minuend 126 -431 Subtrahend + 431 126 Difference 557

13. Let Us Try This!!! 985- 764 = N 456- 231 = N 965- 534= N 548- 438=N 890- 670= N
