Understanding Integer Addition with Counters

Miss C teaches how to use counters to add integers and understand the rules for adding them. She demonstrates with examples of positive and negative integers, introduces the concept of zero pairs, and explains the rules for adding integers with the same and different signs. The video concludes with practice exercises to reinforce the concepts.

What is the result of adding two positive integers using counters?

• The sum is positive.

• The sum is zero.

• The sum is undefined.

• The sum is negative.

When adding two negative integers using counters, what is the result?

• The sum is positive.

• The sum is negative.

• The sum is zero.

• The sum is undefined.

What is a zero pair in the context of integer addition?

• A pair of two negative counters.

• A pair of two positive counters.

• A pair of one positive and one negative counter.

• A pair of counters with the same sign.

How do you determine the sign of the result when adding integers with different signs?

• The result takes the sign of the smaller integer.

• The result is always positive.

• The result takes the sign of the larger integer.

• The result is always negative.

What is the result of 5 + (-7) using the rules for adding integers with different signs?

• -2

• +2

• 0

• +12

When adding integers with the same sign, what should you do?

• Subtract them and keep the sign.

• Add them and keep the sign.

• Subtract them and change the sign.

• Add them and change the sign.

What is the result of 6 + (-5) using counters?

• +11

• -1

• 0

• +1
