Integer Addition: Rules and Examples

This video provides a quick review of adding integers, covering rules for integers with the same and different signs. It includes examples demonstrating how to handle different scenarios, such as integers with different signs, multiple operations, and grouping symbols. The video emphasizes the importance of absolute values and the order of operations in solving integer addition problems.

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

• Subtract the numbers and change the sign

• Add the numbers and change the sign

• Add the numbers and keep the sign

• Subtract the numbers and keep the sign

In the expression -15 + 40, why is the result positive?

• Because the signs are the same

• Because 15 is greater than 40

• Because both numbers are positive

• Because 40 has a greater absolute value and is positive

When adding +12 and -36, what determines the sign of the result?

• The sign of the larger absolute value

• The sign of the first number

• The sign of the smaller absolute value

• The sign of the second number

How do you handle an expression with multiple addition operations?

• Subtract from right to left

• Subtract from left to right

• Add from left to right

• Add from right to left

In an expression with grouping symbols, what should be done first?

• Add all numbers first

• Subtract all numbers first

• Solve inside the grouping symbols first

• Ignore the grouping symbols
