The Math Notes box below describes three useful strategies. Try using ''Pulling Apart'' for this one.
You could think of 275 as 200 + 75 and 187 as 100 + 25 + 62.
You can rearrange the parts so that this sum is 200 + 100 + 75 + 25 + 62.
What is 200 − 97? Can you adjust this for 201 − 97?
Try using ''Give and Take'' for this one!
