# Lesson 3 homework practice subtract integers answer key

### Question:

What is a common Rule for Subtracting Integers?

### Answer:

John has $500 in his savings account. She gets $75 out. Her savings account only has $425 left in it. To find the difference between two whole numbers, you need to take their differences away. Depending on whether the integers are positive, negative, or a mix of both, the value could go up or down. Adding the number being subtracted from the original integer number is the standard form for writing subtraction operations using integers. When subtracting two integers, use the first number plus the inverse of the second number. This is merely a sample. You can get rid of the second digit by adding its inverse to the first digit.
