When performing addition, sometimes you have to find the value of a number that’s missing. This is called finding the missing term.
To find the missing term, you have to do a subtraction. You have to take the end result and subtract the known term.
In the operation ? + 4 = 10, I ask myself what number must be added to 4 to get 10.
I take the final result and I subtract the known term.
Since 10 - 4 = 6, I know the missing term is 6. I can verify if the missing term I found is correct by trying the initial addition again.
To find the missing term, you have to do a subtraction. You have to take the final result and subtract the known term.
In the operation 2 + ? = 5, I ask myself which number must be added to 2 to get 5.
I take the final result and I subtract the known term.
Since 5 - 2 = 3, I know the missing term is 3. I can verify if the missing term I found is correct by trying the initial addition again.
