Subtracting with Integer Chips: A Practical Approach

The video tutorial explains how to use number chips to build intuition for solving subtraction problems involving negative numbers. It demonstrates three examples: -8 - (-2), 4 - 7, and 5 - (-1), showing how positive and negative number chips can cancel each other out to simplify calculations.

What is the result of subtracting negative 2 from negative 8 using number chips?

• -6

• 10

• -10

• 6

How many negative chips are left after subtracting negative 2 from negative 8?

• 8

• 6

• 10

• 2

What does the subtraction of 7 from 4 using number chips result in?

• -3

• 3

• 1

• -1

How many additional pairs of number chips are added to make the subtraction of 7 possible from 4?

• 3

• 6

• 5

• 4

What is the final count of positive number chips after subtracting 7 from 4?

• 3

• 0

• 4

• 7

What is the result of subtracting negative 1 from positive 5 using number chips?

• 5

• 4

• 3

• 6

How many positive number chips are left after subtracting negative 1 from positive 5?

• 6

• 5

• 4

• 7

What is the purpose of adding pairs of positive and negative number chips in the calculations?

• To increase the total number of chips

• To make the chips look colorful

• To balance the equation without changing the total

• To decrease the total number of chips

What does the subtraction of a negative number effectively do to the total?

• Makes it zero

• Increases the total

• Decreases the total

• Does not change the total

In the context of number chips, what does the presence of both positive and negative chips in a pair signify?

• They cancel each other out

• They are irrelevant

• They add up

• They multiply
