Exploring Integer Operations and Their Rules

This video tutorial covers integer operations, focusing on addition rules. It explains how to add integers with the same sign by summing the numbers and retaining the sign. For integers with different signs, it describes finding the difference and using the sign of the number with the larger absolute value. Examples are provided to illustrate these rules.

What is the result of adding two positive integers with the same sign?

• The difference with a negative sign

• The sum with a positive sign

• The difference with a positive sign

• The sum with a negative sign

What happens when you add two negative integers?

• You add the absolute values and the result is negative.

• You add the absolute values and the result is positive.

• You subtract the smaller from the larger and keep the sign of the larger.

• The result is always zero.

What is the sum of 4 + 3?

• -1

• -7

• 1

• 7

What is the sum of -2 + (-6)?

• 4

• -8

• 8

• -4

What is the result of -7 + 3?

• 10

• -10

• 4

• -4

When adding a positive and a negative integer, what determines the sign of the result?

• The sign of the positive integer

• The integer with the smaller absolute value

• The sign of the negative integer

• The integer with the larger absolute value

What is the result of 4 + (-7)?

• -3

• 11

• 3

• -11

How do you find the result of adding two integers with different signs?

• Subtract the smaller absolute value from the larger one

• Add their absolute values

• Multiply their absolute values

• Divide the larger absolute value by the smaller one

If you add a positive and a negative number and get a negative result, what does it imply?

• The negative number has a larger absolute value

• The positive number has a larger absolute value

• None of the above

• The numbers have the same absolute value

In the operation 4 + (-7), which number's sign determines the sign of the answer?

• Both

• 4

• -7

• Neither
