Complete the subtraction sentence - up to three digits

Learning Objectives Identify the minuend, subtrahend, and difference in a subtraction sentence. Use inverse operations (addition) to find a missing minuend in a subtraction sentence. Use inverse operations (subtraction) to find a missing subtrahend in a subtraction sentence. Accurately calculate a missing difference in a subtraction sentence involving three-digit numbers. Apply regrouping techniques correctly when solving subtraction sentences with missing values. Verify their solutions to subtraction sentences using the original operation.

TermDefinitionExample Subtraction SentenceA mathematical statement that shows the relationship between a minuend, a subtrahend, and a difference, typically written as 'minuend - subtrahend = difference'.$543 - 120 = 423$ MinuendThe first number in a subtraction sentence, from which another number is subtracted. It is usually the largest number when dealing with positive differences.In $789 - 234 = 555$, the minuend is $789$. SubtrahendThe second number in a subtraction sentence, which is being subtracted from the minuend.In $789 - 234 = 555$, the subtrahend is $234$. DifferenceThe result or answer obtained when one number is subtracted from another.In $789 - 234 = 555$, the difference is $555$. Inverse OperationsOperations that undo each other. For subtraction, the inverse opera...

Finding the Missing Minuend If $a - b = c$, then $a = c + b$ To find the missing minuend (the first number), add the subtrahend (the number being subtracted) to the difference (the answer). Finding the Missing Subtrahend If $a - b = c$, then $b = a - c$ To find the missing subtrahend (the number being subtracted), subtract the difference (the answer) from the minuend (the first number). Finding the Missing Difference If $a - b = c$, then $c = a - b$ To find the missing difference (the answer), simply subtract the subtrahend from the minuend.
