Adding and Subtracting Integers

The video tutorial explains how to convert subtraction problems into addition problems using integer rules. It demonstrates this process with two examples: 45 minus 62 and 23 minus -72. The first example shows how to handle subtraction resulting in a negative sum, while the second example illustrates a straightforward addition resulting in a positive sum.

What is the first step in rewriting a subtraction problem as an addition problem?

• Add the numbers directly

• Change the sign of the second number

• Multiply both numbers by -1
