Exploring Integer Operations: Addition, Subtraction, Multiplication, and Division

Miss Evans introduces integers and covers all four operations: addition, subtraction, multiplication, and division. She provides rules and examples for each operation, emphasizing the importance of understanding signs and absolute values. The video includes mnemonic devices and practical tips for solving integer problems.

What should you do when adding integers with different signs?

• Add the numbers and keep the original sign.

• Subtract the numbers and keep the sign of the number with the highest absolute value.

• Multiply the numbers.

• None of the above.

How do you handle adding integers with the same sign?

• None of the above.

• Add and keep the sign.

• Add and change the sign.

• Subtract and keep the sign.

In the context of integers, what does 'same signs add and keep' imply?

• None of the above.

• If the signs are the same, subtract the numbers and keep the sign.

• If the signs are the same, add the numbers and change the sign.

• If the signs are the same, add the numbers and keep the sign.

When subtracting integers, what is the first step according to the 'keep change change' method?

• Change both numbers to their absolute values.

• Keep the first number and change the subtraction sign to addition.

• Subtract the second number from the first.

• Change the sign of the second number.

What does 'add the opposite' mean in the context of subtracting integers?

• Keep the first number the same, change subtraction to addition, and take the opposite sign of the second number.

• Change the sign of the first number and add.

• Subtract the numbers as they are.

• None of the above.

What is the correct approach to subtracting integers according to the video?

• None of the above.

• Use the 'keep change change' or 'add the opposite' method.

• Change all subtraction to addition.

• Always subtract the smaller number from the larger one.

What is the result of multiplying a negative number by a positive number?

• Positive

• Negative

• Zero

• Cannot be determined

If you multiply two negative integers, what will the result be?

• Positive

• Negative

• Zero

• The operation is undefined.

What rule applies when dividing two integers with different signs?

• The result is always zero.

• The result cannot be determined without actual values.

• The result is always negative.

• The result is always positive.

What is the outcome when dividing a positive integer by a negative integer?

• Positive

• Zero

• The operation is undefined.

• Negative
