Subtracting Integers and Zero Pairs

The video tutorial from MooMooMath explains how to subtract integers using counting chips or by changing the subtraction sign to addition and altering the sign of the number following it. The instructor uses nickels and pennies as counters to represent positive and negative numbers, respectively. Several example problems are solved using both methods, demonstrating how to handle subtraction of negative numbers effectively.

What are the two methods mentioned for subtracting integers?

• Using addition and multiplication

• Using division and zero pairs

• Using multiplication and division

• Using zero pairs and changing subtraction to addition

What does a nickel represent in the video?

• A negative number

• A subtraction sign

• A positive number

• A zero pair

What happens when a positive and a negative number are combined?

• They cancel each other out

• They add up to a larger number

• They multiply to a larger number

• They divide into smaller numbers

In the example 4 - (-3), what is the result after using zero pairs?

• 3 positives

• 7 positives

• 4 positives

• 1 positive

What is the preferred method for subtracting a negative number?

• Using multiplication

• Changing subtraction to addition

• Using division

• Using zero pairs

In the example -3 - 4, how many negative numbers are left after subtraction?

• 3 negatives

• 7 negatives

• 5 negatives

• 4 negatives

What is the result of 5 - (-2) using the preferred method?

• 7

• 2

• 5

• 3

What can be used as homemade counters for a test or quiz?

• Colored pencils

• Coins of different sizes

• Sheets of paper with positive and negative signs

• Calculator

What is the result of 2 - (-3) using the preferred method?

• 1

• 5

• 0

• 3

What is the main topic of the video?

• Adding integers

• Dividing integers

• Subtracting integers

• Multiplying integers
