Adding Integers Using Rules

The video tutorial explains how to add integers using three simple rules. It begins with an introduction to integers, followed by rules for adding integers with the same sign, different signs, and opposite integers. The tutorial also provides historical context on the acceptance of negative numbers, highlighting Brahmagupta's contributions. Finally, it includes practice problems to reinforce the rules learned.

What is the result of adding two positive integers?

• The sum is negative.

• The sum is zero.

• The sum is positive.

• The sum is the same as one of the integers.

When adding integers with different signs, what should you do?

• Multiply their absolute values.

• Divide their absolute values.

• Subtract their absolute values and keep the sign of the larger integer.

• Add their absolute values and keep the sign of the smaller integer.

Which civilization was among the first to accept negative numbers?

• The Greeks

• The Egyptians

• The Indians

• The Romans

What is the result of adding a number to its opposite?

• The sum is negative.

• The sum is double the number.

• The sum is zero.

• The sum is the number itself.

What is the additive inverse property?

• Adding a number to itself results in zero.

• Multiplying a number by its opposite results in zero.

• Adding a number to its opposite results in zero.

• Subtracting a number from itself results in zero.

In the problem +13 + +7, what is the result?
