Integer Operations and Additive Inverses

The video tutorial by Miss Go covers the subtraction of integers and rational numbers. It explains the rule that subtracting a number is equivalent to adding its opposite. The lesson uses an integer game to demonstrate how removing or subtracting positive and negative cards affects scores. Through examples, the concept of additive inverse is illustrated, showing that subtracting a number and adding it back returns to the original value. The tutorial emphasizes understanding subtraction through the inverse relationship with addition.

What is the main rule of subtraction discussed in the lesson?

• Subtracting a number is the same as adding its opposite.

• Subtracting a number is the same as multiplying by zero.

• Subtracting a number is the same as dividing by one.

• Subtracting a number is the same as adding one.

In the integer game, what happens when you select a positive card?

• The score increases.

• The score remains the same.

• The score decreases.

• The score doubles.

What effect does discarding a negative card have on your score in the integer game?

• It decreases the score.

• It has no effect on the score.

• It increases the score.

• It doubles the score.

How does selecting a negative card affect your score in the integer game?

• It has no effect on the score.

• It decreases the score.

• It increases the score.

• It doubles the score.

What is the additive inverse of a number?

• The number divided by two.

• The opposite sign of the number.
