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
