To rewrite three-digit addition problems, first, align the numbers vertically by their place values (hundreds, tens, and units). Then, add the digits starting from the rightmost column, carrying over any value that exceeds ten to the next column on the left. Continue this process for each column until all digits have been added. Finally, write the sum below the line, ensuring to include any carry-over values in the appropriate place.
That would be 16. You do the division first, then the addition.

If 20/50 questions were addition problems, this is equal to 2/5 or two fifths.

To find 16 - 9 using an addition sentence, you can rewrite it as 9 + ? = 16. This shows that you need to add a certain number to 9 to reach 16. The answer is 7, so the complete addition sentence is 9 + 7 = 16.

Oh, isn't that a happy little question! To rewrite -4-(-6) as an addition problem, we can change it to -4 + 6. Remember, when you have a subtraction of a negative number, it's like adding the positive version of that number. Just like adding a happy little tree to your painting, we're turning this into a positive addition problem to brighten things up!
-2+5 Addition is commutative, so you can rewrite this as 5-2 5-2=3
