Activity 2.3 Subtraction of Integers
Your Task
Use this applet to explore the subtraction of integers.
Follow the representation below to solve for the difference of the given integers. A checkmark will appear if your answer is correct, while a "try again" message will display if it is incorrect.
Next, answer the questions below. Finally, identify and generalize about the subtraction process in relation to the sign of the subtrahends.
Observing
In which direction does the subtrahend move from the minuend if the subtrahend is positive?
Observing
In which direction does the subtrahend move from the minuend if the subtrahend is negative?
Collecting Data
Conjecturing - Positive Subtrahend
Make a conjecture about the process of subtraction when the subtrahend is positive.
Collecting Data
Conjecturing - Negative Subtrahend
