Clare uses these equations to solve 300-178. So you agree with her work? Explain.
178+2=180
180+20=200
200+100=300
Her equations show that 178+122 equals 300. She decided to count up from 178 instead of taking away 122 away from 300.

John says that to find the value of the expression
547-167 he can subtract 200 and then add 33.
Explain why he is correct
John is correct because subtracting 200 and adding back 33 is the same as subtracting 33 fewer. 33 fewer than 200 is 167.
