Adding Integers and Rational Numbers

The lesson covers the rules for adding integers and rational numbers. It explains how to add integers with the same sign by summing their absolute values and keeping the common sign. For integers with opposite signs, it involves subtracting the smaller absolute value from the larger one and using the sign of the number with the larger absolute value. The lesson also extends these rules to rational numbers, demonstrating with examples.

What is the main focus of today's lesson?

• Subtracting rational numbers

• Dividing integers

• Multiplying integers

• Efficiently adding integers and rational numbers

When adding two positive integers, what is the result?

• A smaller positive number

• A negative number

• A larger positive number

• Zero

What happens when you add two negative integers?

• You get a larger negative number

• You get zero

• You get a positive number

• You get a smaller negative number

What is the rule for adding integers with the same sign?

• Add the numbers and change the sign

• Subtract the smaller number from the larger

• Add the absolute values and use the common sign

• Subtract the absolute values and use the common sign

How do you determine the sign of the sum when adding integers with opposite signs?

• Use the sign of the smaller absolute value

• Always use a positive sign

• Always use a negative sign

• Use the sign of the larger absolute value

What is the first step in adding integers with opposite signs?

• Add the numbers directly

• Divide the numbers

• Subtract the absolute values

• Multiply the numbers

How do the rules for adding rational numbers compare to those for integers?

• They are completely different

• They are the same

• They are similar but not the same

• They only apply to fractions

What is the absolute value of a number?

• The distance from zero, always positive

• The negative of the number

• The number itself

• The number squared

What is the final step in adding rational numbers?

• Divide the numbers

• Ignore the signs

• Multiply the numbers

• Use the sign of the number with the greater absolute value

What is the key takeaway from the lesson on adding integers and rational numbers?

• Ignore the absolute values

• Only add positive numbers

• Use the same rules for both integers and rational numbers

• Always subtract the numbers
