Understanding Integer Subtraction

The video tutorial explains how to subtract positive and negative integers by converting the subtraction problem into an addition problem. It demonstrates this method with examples, showing how to change the signs of the integers involved to simplify the calculation.

What is the first step in converting a subtraction problem involving integers into an addition problem?

• Change the sign of the first number

• Change the sign of the second number

• Change the signs of both numbers

• Add both numbers directly

In the example provided, what is the result of converting 14 - (-3) into an addition problem?

• 3

• 14

• 17

• 11

When converting a subtraction problem to addition, what happens to a positive number?

• It doubles

• It remains positive

• It becomes negative

• It becomes zero

In the second example, what is the result of converting 14 - 3 into an addition problem?

• -3

• -7

• -11

• -17

What is the final result of the subtraction problem -14 - 3 after converting it to an addition problem?

• -3

• -11

• -17

• -7
