Key Concepts & Vocabulary
TermDefinitionExample
SubtractionThe mathematical operation of taking one number or quantity away from another, or finding the difference between two numbers.If you have 5 candies and eat 2, you perform subtraction to find out how many are left: $5 - 2 = 3$.
Word ProblemA math problem presented in sentences or a short story, requiring you to read and understand the context to determine the correct operation and solve it.''There were 4 birds on a tree. 1 bird flew away. How many birds are left?'' is a word problem.
Subtraction KeywordsSpecific words or phrases in a word problem that often indicate subtraction is the required operation.Keywords include 'left,' 'remain,' 'take away,' 'fewer,' 'how many more,' 'differe...

Core Formulas
Basic Subtraction Formula
$M - S = D$
This formula represents the core of subtraction, where $M$ is the Minuend (the starting amount), $S$ is the Subtrahend (the amount being taken away), and $D$ is the Difference (the result). For numbers up to 5, the minuend will always be greater than or equal to the subtrahend.
Identifying Subtraction Keywords
Look for words like 'left', 'remain', 'take away', 'how many more', 'fewer', 'difference'.
These keywords are strong indicators that the word problem requires subtraction to find the solution. Carefully read the problem to understand if quantities are being removed or compared.

Challenging
According to the tutorial, one way to verify the answer to 5 - 2 = 3 is to check if the answer is reasonable. Another method is to use the inverse operation. Which numerical sentence uses the inverse operation to verify this subtraction fact?
A.3 + 2 = 5
B.5 + 3 = 8
C.5 / 2 = 2.5
D.3 * 2 = 6
Challenging
Which of the following questions is structurally a 'comparison' or 'finding the difference' problem, rather than a 'take away' problem?
A.tree had 5 apples. 4 apples fell off. How many are on the tree?
B.You had $5 and spent $4. How much money is left?
C.5 students were in the library. 4 went to class. How many remain?
