Use Place Value Strategy to solve these problems.
161 - 78 70 - 60 = 10 / 8 - 1 = 7 / 10 + 7 = 17 / 100 - 17 = 83
90 - 37 90 - 30 = 60 / 60 - 7 = 53
211 - 69 200 - 60 = 140 / 11 - 9 = 2 / 140 + 2 = 142
104 - 58 100 - 50 = 50 / 8 - 4 = 4 / 50 - 4 = 46
122 - 85 80 - 20 = 60 / 100 - 60 = 40 / 5 - 2 = 3 / 40 - 3 = 37
In the Algebra Group, I solved these problems by using the Place Value Strategy.
