In a subtraction, sometimes the value of a missing number has to be found. This is called finding the missing term.
To find the missing term, you must perform an addition. You add the answer to the known term.
In the operation ? - 4 = 2, I ask myself which number, when subtracted by 4, results in 2.
I add the answer to the known term.
Since 2 + 4 = 6, the missing term is 6. To verify if the missing term is correct, I can try the original subtraction.
In this case, finding the missing term requires a subtraction. You must subtract the answer from the first number.
In the operation 8 - ? = 3, I ask myself which number, when subtracted from 8, results in 3.
I subtract the answer from the first number.
In 8 - 3 = 5, the missing term is 5. To verify if the missing term is correct, I can try the original subtraction.
