Help pleasee me give bralienst, stars and thanks

(Going from left to right)

Box #1=3

Box #2=5

Box #3=7

Box #4=2

Step-by-step explanation:

For Box #4, there is nothing for the 2 to subtract from so it just goes down

For Box #3, it has to be 7, because nothing can be subtracted from 1 to get 3, so you would have to bring a 1 from the 4 to the left to make the 1 to a 10. 10-7=3

For Box #2 and 1, 3(we changed it in the last step) -9 = a negative number so we have to bring a 1 from the number to the left. This is a hard step but what you have to do it look at the bottom number, which is a 2, so that number had to be a 3 because 3-1=2. 4 becomes 14, and 14-9=5

Hope this helps, if it did, please consider giving me brainliest, it will help me a lot. If you have any questions, feel free to ask.

Have a good day! :)
