Subtraction of Integers

The video tutorial explains the concept of additive inverse and its application in subtraction. It covers how to subtract negative integers from positive ones, positive integers from negative ones, and larger integers from smaller ones using both tiles and a number line. The tutorial also demonstrates subtracting negative integers from each other, emphasizing the conversion of subtraction into addition by using additive inverses.

What is the additive inverse of a number?

• A number that is double the original

• A number that, when added to the original, results in zero

• A number that is half of the original

• A number that, when subtracted from the original, results in zero
