Study Notes

Subtraction is the arithmetic operation of finding the difference between two numbers.
In the subtraction problem 500 - 425, the minuend is 500 and the subtrahend is 425.
The difference represents the value that is left over when 425 is taken away from 500.

Word problems present mathematical situations in narrative form, requiring students to identify the relevant information and apply the appropriate mathematical operation(s) to find the solution.
Example: "Maria had 500 stickers. She gave 425 stickers to her friend. How many stickers does Maria have left?"
Students need to identify that they must subtract "425 from 500" to find the solution.

Place value refers to the value of a digit in a number based on its position.

The subtraction of integers involves considering the direction and magnitude of numbers on a number line.
Example: 500–425 = 75.

The number line is a visual representation of numbers arranged sequentially, which helps in understanding the concepts of order, magnitude, and distance between numbers.
Using the number line to illustrate subtraction.
A number line can be used to visualize the subtraction. Starting at 500, count backward 425 units to arrive at the difference.
The number line provides a visual understanding of how to solve the problem concretely.
Subtracting using a number line involves showing the movement from one number to another on the number line and determining the difference.
Understanding the impact of positive and negative signs on the solutions to equations involving integers.
