Let's practice adding 100 and subtracting 100 from a number! Remember - we are only going to be changing the digit in the HUNDREDS place! So, if our number is 234, we will only be changing the 2, not the 3 or the 4! Click to start your response. In the first column, use the tool to write 100 more than the number. In the second column, use the tool to write 100 less than the number. You can use scratch paper or your whiteboard if that helps you! Double-check your work and click to submit your work!
