what do i put in the blanks

Answer:
1. 952 - 800 = 152
2. 152 - 120 = 32
3. 32 - 32 = 0
Step-by-step explanation:
In this type of situation, always subract the top number and the result number to get your middle number answer. For an example, in the 3rd one, I know that if I subtract 952 - 152 it equals 800. I also know that if I subtract 952 - 800 it equals 152. And that's how you get your solution! I hope this was helpful. :)
