Subtracting Integers
Grade 6 · Math · Integers and the Number Line · Indiana, USA
Lesson Summary
Subtract integers by adding the opposite of the number being subtracted.
Explanation
To subtract an integer, change the subtraction to addition and flip the sign of the second number. So 5 - (-3) becomes 5 + 3, which equals 8. And -4 - 6 becomes -4 + (-6), which equals -10. This rule works because subtracting a negative is the same as adding a positive, and subtracting a positive is the same as adding a negative. Once you rewrite the problem as addition, you can use the integer addition rules you already know.
